R3303-HP HSR6800 Routers Layer 3 - IP Routing Command Reference

168
ip-prefix ip-prefix-name: Specifies the name of an IP prefix list that is used to filter redistributed routes, a
case-sensitive string of 1 to 19 characters. For IP prefix list configuration information, see "Routing policy
configuration commands."
route-policy route-policy-name: Specifies the name of a routing policy that is used to filter redistributed
routes, a case-sensitive string of 1 to 63 characters. For routing policy configuration information, see
"Routing policy configuration commands."
protocol: Filters routes redistributed from the routing protocol, which can be BGP, direct, IS-IS, OSPF, RIP,
or static.
process-id: Specifies a process by its ID in the range of 1 to 65535. It is optional only when the protocol
is IS-IS, OSPF, or RIP.
Usage guidelines
To reference an advanced ACL (with a number from 3000 to 3999) in the command, configure the ACL
in one of the following ways:
• To deny/permit a route with the specified destination, use the rule [ rule-id ] { deny | permit } ip
source sour-addr sour-wildcard command.
• To deny/permit a route with the specified destination and mask, use the rule [ rule-id ] { deny |
permit } ip source sour-addr sour-wildcard destination dest-addr dest-wildcard command.
The source keyword specifies the destination address of a route, and the destination keyword specifies
the subnet mask of the route. (The subnet mask must be valid; otherwise, the configuration is ineffective.)
Examples
# Reference ACL 2000 to filter redistributed routes.
<Sysname> system-view
[Sysname] acl number 2000
[Sysname-acl-basic-2000] rule deny source 192.168.10.0 0.0.0.255
[Sysname-acl-basic-2000] quit
[Sysname] isis 1
[Sysname-isis-1] filter-policy 2000 export
# Configure ACL 3000 to permit only route 113.0.0.0/16 to pass, and reference ACL 3000 to filter
redistributed routes.
<Sysname> system-view
[Sysname] acl number 3000
[Sysname-acl-adv-3000] rule 10 permit ip source 113.0.0.0 0 destination 255.255.0.0 0
[Sysname-acl-adv-3000] rule 100 deny ip
[Sysname-acl-adv-3000] quit
