Configuring BGP to Advertise Default Routes to Peers

Before configuring BGP to send default routes to peers, configure basic BGP functions.

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> ]
Or run 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> ]

A BGP device is configured to send default routes to a peer or peer group.

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.
Run the display bgp multicast routing-table [ ip-address [ mask-length [ longer-prefixes ] | mask [ longer-prefixes ] ] ] command to check received MBGP default routes.
