R3303-HP HSR6800 Routers MPLS Command Reference

382
A limit configured in IPv6 VPN view applies to only the IPv6 VPN.
IPv6 VPN prefers the limit configured in IPv6 view over the limit configured in VPN instance view.
Examples
# Specify that VPN instance vpn1 supports up to 1000 routes, and when routes exceed the limit, can
receive new routes but generates a system log message.
<Sysname> system-view
[Sysname] ip vpn-instance vpn1
[Sysname-vpn-instance-vpn1] route-distinguisher 100:1
[Sysname-vpn-instance-vpn1] routing-table limit 1000 simply-alert
# Specify that the IPv6 VPN vpn3 supports up to 1000 routes, and when routes reach 70% of the limit,
can receive new routes but generates a system log message.
<Sysname> system-view
[Sysname] ip vpn-instance vpn3
[Sysname-vpn-instance-vpn3] route-distinguisher 100:3
[Sysname-vpn-instance-vpn3] ipv6-family
[Sysname-vpn-ipv4-vpn3] routing-table limit 1000 70
rr-filter (BGP-VPNv6 subaddress family view)
Use rr-filter to create an RR reflection policy so that only IBGP routes whose Extended Communities
attribute matches the specified one are reflected.
Use undo rr-filter to restore the default.
Syntax
rr-filter extended-community-number
undo rr-filter
Default
An RR does not filter the reflected routes.
Views
BGP-VPNv6 subaddress family view
Default command level
2: System level
Parameters
extended-community-number: Specifies the number of the Extended Communities attribute supported by
the RR, in the range of 1 to 199.
Usage guidelines
By configuring different RR reflection policies on different RRs, you can implement load balancing among
the RRs.
Examples
# In BGP-VPNv6 subaddress family view, specify an Extended Communities attribute for the RR to filter
the incoming VPNv6 route update packets.
