Layer 3 Routing Commands 1347
unlimited—Do not enforce any prefix limit. Use this option when
inbound filtering will reduce the number received prefixes such that they
will fit in the routing table. Exceeding the capacity of the routing table will
cause the adjacency to be shut down unless the warning-only option is
configured.
warning-only—(Optional) If BGP receives more than the maximum
number of prefixes, BGP writes a log message rather than shutting down
the adjacency.
Default Configuration
There is no prefix limit by default. The default warning threshold is 75%. A
neighbor that exceeds the limit is shut down by removing the adjacency
unless the warning-only option is configured.
Command Mode
IPv6 Address Family Configuration mode
User Guidelines
If the peering session is shut down, the adjacency stays down until clear ip
bgp is issued for the neighbor.
Different limits can be set for IPv4 and IPv6. In IPv6 address family mode,
the command accepts either an IPv4 or an IPv6 address. The VLAN interface
must also be specified if a link-local address is specified.
Command History
Introduced in version 6.2.0.1 firmware.

console(config-router-af)#neighbor FE80::0202:B3FF:FE1E:8329 interface vlan
