Clearing BGP4+ information
46
The suppress-map <map-name> parameter prevents the more specific routes contained in the
specified route map from being advertised.
The advertise-map <map-name> parameter configures the switch to advertise the more specific
routes in the specified route map.
The attribute-map <map-name> parameter configures the switch to set attributes for the aggregate
routes based on the specified route map.
NOTE
For the suppress-map, advertise-map, and attribute-map parameters, the route map must already
be defined.
To remove an aggregate route from a BGP4 neighbor advertisement, use the no form of this
command without any parameters.
Using route maps
You can use a route map to filter and change values in BGP4+ routes. Currently, you can apply a
route map to IPv6 unicast routes that are independent of IPv4 routes.
To configure a route map to match on IPv6 unicast routes, enter commands such as the following.
BigIron RX(config)# router bgp
BigIron RX(config-bgp)# address-family ipv6 unicast
BigIron RX(config-bgp-ipv6u)# neighbor 2001:eff3:df78::67 remote-as 1001
BigIron RX(config-bgp-ipv6u)# neighbor 2001:eff3:df78::67 route-map in map1
BigIron RX(config-bgp-ipv6u)# exit
BigIron RX(config)# ipv6 prefix-list ipv6_uni seq 10 permit 2001:eff3::/32
BigIron RX(config)# route-map map1 permit 10
BigIron RX(config-routemap-map1)# match ipv6 address prefix-list ipv6_uni
This example configures a route map named “map1” that permits incoming IPv6 unicast routes
that match the prefix list named “ipv6_uni” (2001:eff3::/32). Note that you apply the route map
while at the BGP4+ unicast address family configuration level.
Clearing BGP4+ information
This section contains information about clearing the following for BGP4+:
• Route flap dampening.
• Route flap dampening statistics.
• Neighbor information.
• BGP4+ routes in the IPv6 route table.
• Neighbor traffic counters.
NOTE
The clear commands implemented for BGP4+ correspond to the clear commands implemented for
IPv4 BGP. For example, you can specify the clear ipv6 bgp flap-statistics command for IPv6 and the
clear ip bgp flap-statistics for IPv4.
