Configuring A Bgp4+ Peer Group - Dell PowerConnect B-RX Configuration Manual

Configuring a route map
To configure a route map that filters routes advertised to a neighbor or sets up a global next hop for
packets destined for the neighbor with the IPv6 link-local address fe80:4393:ab30:45de::1, enter
commands such as the following (start at the BGP4+ unicast address family configuration level).
BigIron RX(config-bgp-ipv6u)# neighbor fe80:4398:ab30:45de::1 route-map out
next-hop
BigIron RX(config-bgp-ipv6u)# exit
BigIron RX(config)# route-map next-hop permit 10
BigIron RX(config-route-map)# match ipv6 address prefix-list next-hop-ipv6
BigIron RX(config-route-map)# set ipv6 next-hop 2011:e0ff:3764::34
This route map applies to the BGP4+ unicast address family under which the neighbor route-map
command is entered. This route map applies to the outgoing routes on the neighbor with the IPv6
link-local address fe80:4393:ab30:45de::1. If an outgoing route on the neighbor matches the
route map, the route is distributed through the next hop switch with the global IPv6 address
2011:e0ff:3764::34.
Syntax: neighbor <ipv6-address> route-map [in | out] <name>
The <ipv6-address> parameter specifies the IPv6 link-local address of the neighbor. A link-local
address has a fixed prefix of FE80::/64. You must specify the <ipv6-address> parameter in
hexadecimal using 16-bit values between colons as documented in RFC 2373.
The in keyword applies the route map to incoming routes. The out keyword applies the route map to
outgoing routes.
The <name> parameter specifies a route map name.
Syntax: route-map <name> deny | permit <sequence-number>
The name parameter specifies a route map name.
The deny keyword denies the distribution of routes that match the route map. The permit keyword
permits the distribution of routes that match the route map.
The <sequence-number> parameter specifies a sequence number for the route map statement.
Syntax: match ipv6 address prefix-list <name>
The match ipv6 address prefix-list command distributes any routes that have a destination IPv6
address permitted by a prefix list.
The <name> parameter specifies an IPv6 prefix list name.
Syntax: set ipv6 next-hop <ipv6-address>
The <ipv6-address> parameter specifies the IPv6 global address of the next-hop switch. You must
specify the <ipv6-address> parameter in hexadecimal using 16-bit values between colons as
documented in RFC 2373.

Configuring a BGP4+ peer group

If a switch has multiple neighbors with similar attributes, you can configure a peer group, then add
neighbors to the group instead of configuring neighbors individually for all parameters as described
in "Configuring BGP4+ neighbors using global or site-local IPv6 addresses"
"Adding BGP4+ neighbors using link-local addresses"
