Configuring BGP to Advertise Default Routes to Peers
Pre-configuration Tasks
Before configuring BGP to send default routes to peers, configure basic BGP functions.
Procedure
- Run system-view
The system view is displayed.
- Run bgp { as-number-plain | as-number-dot }
The BGP view is displayed.
- Enter the corresponding address family view
based on network type to configure BGP devices on networks.
Run ipv4-family { unicast | multicast }
The IPv4 address family view is displayed.
Run ipv6-family [ unicast ]
The IPv6 address family view is displayed.
- Run peer { group-name | ipv4-address | ipv6-address } default-route-advertise [ route-policy route-policy-name ] [ conditional-route-match-all { ipv4-address1 { mask1 | mask-length1 } } &<1-4> | conditional-route-match-any { ipv4-address2 { mask2 | mask-length2 } } &<1-4> ]
peer { group-name | ipv4-address | ipv6-address } default-route-advertise [ route-policy route-policy-name ] [ conditional-route-match-all { ipv6-address1 prefix-length1 } &<1-4> | conditional-route-match-any { ipv6-address2 prefix-length2 } &<1-4> ]
Or:
A BGP device is configured to send default routes to a peer or peer group.
Verifying the Configuration
Run the display bgp routing-table [ ipv4-address [ mask | mask-length [ longer-prefixes ] ] ] command to check received BGP default routes.
- Run the display bgp multicast routing-table [ ip-address [ mask-length [ longer-prefixes ] | mask [ longer-prefixes ] ] ] command to check received MBGP default routes.
