Configuring IPv6 MBGP route summarization, Advertising a default route to a peer or peer group

Page 360 highlights

Step Command 4. Enable default route redistribution into the IPv6 MBGP routing table. default-route imported 5. Enable route redistribution from another routing protocol. import-route protocol [ process-id [ med med-value | route-policy route-policy-name ] * ] Description Optional. By default, default route redistribution is not allowed. If the default-route imported command is not configured, using the import-route command cannot redistribute any IGP default route. Not enabled by default. Configuring IPv6 MBGP route summarization To reduce the routing table size on medium and large BGP networks, you must configure route summarization on IPv6 MBGP routers. BGP supports only manual summarization of IPv6 multicast routes. To configure IPv6 MBGP route summarization: Step 1. Enter system view. 2. Enter BGP view. 3. Enter IPv6 MBGP address family view. 4. Configure manual route summarization. Command system-view bgp as-number ipv6-family multicast aggregate ipv6-address prefix-length [ as-set | attribute-policy route-policy-name | detail-suppressed | origin-policy route-policy-name | suppress-policy route-policy-name ]* Remarks N/A N/A N/A Not configured by default. Advertising a default route to a peer or peer group Step 1. Enter system view. 2. Enter BGP view. 3. Enter IPv6 MBGP address family view. Command system-view bgp as-number ipv6-family multicast peer { ipv6-group-name | 4. Advertise a default route to an ipv6-address } IPv6 MBGP peer or peer default-route-advertise group. [ route-policy route-policy-name ] Remarks N/A N/A N/A Not advertised by default. With the peer default-route-advertise command executed, the router sends a default route with the next hop as itself to the specified IPv6 MBGP peer or the specified peer group, regardless of whether the default route is available in the routing table. 349

Optional.
By default, default route
redistribution is not allowed.
If the
default-route imported
command is not configured, using
the
import-route
command cannot
redistribute any IGP default route.

Configuring IPv6 MBGP route summarization
To reduce the routing table size on medium and large BGP networks, you must configure route
summarization on IPv6 MBGP routers. BGP supports only manual summarization of IPv6 multicast routes.

whether the default route is available in
the routing table.
