Displaying IPv6 MBGP information

The ve <num> parameter specifies a virtual interface.
The null0 parameter is the same as dropping the traffic.
The distance <num> parameter sets the administrative distance for the route.
The <cost> parameter specifies the cost metric of the route. Possible values are: 1 - 6 Default
value: 1
Regardless of the administrative distances, the BigIron RX Series router always prefers directly
connected routes over other routes.
Aggregating routes advertised to IPv6 BGP neighbors
By default, the device advertises individual MBGP routes for all the multicast networks. The
aggregation feature allows you to configure the device to aggregate routes in a range of networks
into a single CIDR number.
To aggregate MBGP routes, enter the following command.
BigIron RX(config-bgp-router)# aggregate-address 8eff::0/32
Syntax: aggregate-address <ipv6-addr> <ipv6-mask> [as-set] [summary-only] [suppress-map
<map-name>] [advertise-map <map-name>] [attribute-map <map-name>]
The <ipv6-addr> and <ipv6-mask> parameters specify the aggregate value for the networks.
The as-set parameter causes the router to aggregate AS-path information for all the routes in the
aggregate address into a single AS-path.
The summary-only parameter prevents the router from advertising more specific routes contained
within the aggregate route.
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 device to advertise the more specific
routes in the specified route map.
The attribute-map <map-name> parameter configures the device 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.
Displaying IPv6 MBGP information
All of the IPv6 BGP show commands have IPv6 MBGP equivalents. Use ipv6 mbgp instead of ipv6
bgp in the command syntax. For example, to display the MBGP route table, enter the show ipv6
mbgp routes command instead of the show ipv6 bgp routes command.
Table 223 lists the MBGP
show commands and describes their output. For information about a command, refer to Chapter
27, “Configuring BGP4 (IPv4 and IPv6)” .
