If this option is not specified, the command applies to the public network.
Views Interface view Default command level 2: System level Usage guidelines IP multicast routing must be enabled in the corresponding instance before this command can take effect. IGMP must be enabled on an interface before any other IGMP feature configured on the interface can take effect. Examples # Enable IP multicast routing on the public network, and enable IGMP on Ethernet 1/1.
igmp-snooping fast-leave command or the fast-leave (IGMP-snooping view) command, because these two commands are effective on VLANs with IGMP enabled on their VLAN interfaces. Related commands • fast-leave (IGMP view) • fast-leave (IGMP-snooping view) • igmp last-member-query-interval • igmp-snooping fast-leave Examples # Enable fast-leave processing on Ethernet 1/1.
Command MSR900 MSR93X MSR20-1 X MSR20 MSR30 MSR50 MSR100 0 igmp group-limit Value range for limit: 1 to 900 (default). Value range for limit: 1 to 900 (default). Value range for limit: 1 to 900 (default). Value range for limit: 1 to 900 (default). Value range for limit: 1 to 1024 (default). Value range for limit: 1 to 2048 (default). Value range for limit: 1 to 900 (default). Examples # Allow Ethernet 1/1 to join up to 128 multicast groups.
Usage guidelines For a device that supports both IGMP snooping and IGMP, you can also use the group-policy (IGMP-snooping view) command to control the multicast groups that hosts in a VLAN can join, achieving the same result as igmp group-policy. If you have configured a multicast group filter on a VLAN interface to control the multicast groups that the hosts on the interface can join, HP recommends you to configure the same multicast group filter in the corresponding VLAN.

Views Public network PIM view, VPN instance PIM view Default command level 2: System level Parameters hash-length: Specifies a hash mask length in the global scope zone. The value range is 0 to 32. If you do not specify this argument, the corresponding global setting is used. priority: Specifies the priority of the C-BSR in the global scope zone. The value range is 0 to 255. A larger value means a higher priority. If you do not specify this argument, the corresponding global setting is used.
Parameters group-address: Specifies a multicast group address in the range of 239.0.0.0 to 239.255.255.255. mask: Specifies the mask of the multicast group address. mask-length: Specifies the mask length of the multicast group address. The value range is 8 to 32. hash-length: Specifies a hash mask length in the admin-scope zone that corresponds to the specified multicast group. The value range is 0 to 32. If you do not specify this argument, the corresponding global setting is used.
Parameters hash-length: Specifies a hash mask length in the range of 0 to 32. Examples # Set the global hash mask length to 16 on the public network. system-view [Sysname] pim [Sysname-pim] c-bsr hash-length 16 # Set the global hash mask length to 16 in VPN instance mvpn.
[Sysname-pim-mvpn] c-bsr holdtime 150 Related commands • c-bsr • c-bsr interval c-bsr interval (PIM view) Use c-bsr interval to configure the BS period, namely, the interval at which the BSR sends bootstrap messages. Use undo c-bsr interval to restore the default. Syntax c-bsr interval interval undo c-bsr interval Default This formula determines the BS period value: BS period = (BS timeout – 10) ÷ 2.
undo c-bsr priority Default The C-BSR priority is 64. Views Public network PIM view, VPN instance PIM view Default command level 2: System level Parameters priority: Specifies the priority of the C-BSR, in the range of 0 to 255. A larger value means a higher priority. Examples # Set the global C-BSR priority to 5 on the public network. system-view [Sysname] pim [Sysname-pim] c-bsr priority 5 # Set the global C-BSR priority to 5 in VPN instance mvpn.
acl-number: Specifies a basic ACL in the range of 2000 to 2999. This ACL defines a range of multicast groups the C-RP is going to serve, rather than defining a filtering rule. Any group range that matches the permit statement in the ACL is advertised as an RP served group, but the configuration that matches other statements, like deny, does not take effect. priority: Specifies the priority of the C-RP, in the range of 0 to 255. The default is 192. A larger value means a lower priority.
Use undo c-rp advertisement-interval to restore the default. Syntax c-rp advertisement-interval interval undo c-rp advertisement-interval Default The C-RP-Adv interval is 60 seconds. Views Public network PIM view, VPN instance PIM view Default command level 2: System level Parameters interval: Specifies a C-RP-Adv interval in seconds, in the range of 1 to 65535. Examples # Set the global C-RP-Adv interval to 30 seconds on the public network.
Parameters interval: Specifies a C-RP timeout timer in seconds, in the range of 1 to 65535. Usage guidelines Because a non-BSR router refreshes its C-RP timeout timer through BSR bootstrap messages, to prevent loss of C-RP information in BSR bootstrap messages, make sure the C-RP timeout timer is not smaller than the interval at which the BSR sends bootstrap messages.

If you both reference a routing policy and use the peer { ipv6-group-name | ipv6-address } preferred-value value command to set a preferred value for routes from a peer, the routing policy sets the specified preferred value for matching routes. Routes that do not match the routing policy use the value set with the peer preferred-value command. If the preferred value specified in the routing policy is zero, the matching routes also use the value set with the peer preferred-value command.
Examples # Disable updates sent to IPv6 MBGP peer 1:2::3:4 from carrying private AS numbers.

undo reflect between-clients Default Route reflection between clients is enabled. Views IPv6 MBGP address family view Default command level 2: System level Usage guidelines After a route reflector is configured, it reflects the routes of a client to the other clients. If the clients of a route reflector are fully meshed, you need to disable route reflection between clients to reduce routing costs.
Usage guidelines The router ID of the route reflector is the ID of the cluster. You can configure multiple route reflectors to improve network stability. If a cluster has multiple route reflectors, use the reflector cluster-id command to specify the same cluster ID for these route reflectors to avoid routing loops. Examples # Set 50 as the cluster ID for the route reflector, which is one of multiple route reflectors in the cluster.
