Configuring IPv6 MBGP
Advertising routes from the local AS to MBGP
You can configure the device to advertise directly-connected and static multicast routes from the
local AS to other ASs using the following methods:
•
•
NOTE
You can configure the device to advertise directly-connected networks into MBGP using the network
command. You are not required to use redistribution or configure static multicast routes.
Configuring a network prefix to advertise
By default, the BigIron RX advertises MBGP routes only for the networks you identify using the
network command or that are redistributed into MBGP from IPv6 multicast route tables.
NOTE
The exact route must exist in the IPv6 multicast route table so that the device can create a local
MBGP route.
To configure the device to advertise network 207.95.22.0/24 as a multicast route, enter the
following command.
BigIron RX(config-bgp-ipv6m)# network 207.95.22.0 255.255.255.0
Syntax: network <ipv6-addr> <ipv6-mask> [route-map <map-name>] [backdoor] [weight <num>]
The <ipv6-addr> is the network number and the <ipv6-mask> specifies the network mask.
The route-map <map-name> parameter specifies the name of the route map you want to use to set
or change BGP4 attributes for the network you are advertising. The route map must already be
configured.
The backdoor parameter changes the administrative distance of the route to this network from the
EBGP administrative distance (20 by default) to the Local BGP weight (200 by default), thus tagging
the route as a backdoor route.
The weight <num> parameter specifies a weight to be added to routes to this network.
Enabling redistribution of directly-connected multicast routes into MBGP
To redistribute a directly-connected multicast route into MBGP enable redistribution of
directly-connected routes into MBGP, using a route map to specify the routes to be redistributed.
Here is an example.
1190
For directly-connected routes:
•
Enable redistribution of directly-connected multicast routes.
For indirectly-connected routes:
•
Configure static IPv6 multicast routes. The corresponding IPv6 route must be present in
the IPv6 multicast table.
•
Explicitly configure network prefixes to advertise (network command).
