9.4.9 Checking the Configurations

After the advertising and receiving of BGP4+ routes are controlled, you can check the advertised
routes that match the specified filter.
Prerequisites
Controlling the advertising and receiving of BGP4+ routing information has been configured.
Procedure
l
Issue 02 (2014-09-30)
The route-refresh capability is enabled.
By default, the route-refresh capability is enabled.
If the route-refresh capability is enabled on all the BGP4+ devices, the local device
advertises the route-refresh messages to its peer if the BGP4+ route policies change.
The peer receiving this message sends its routing information to the local device again.
In this way, the BGP4+ routing table is updated dynamically and the new policies are
applied without interrupting the BGP4+ connections.
Keeping All Route Updates of Peers

1.

Run:
system-view
The system view is displayed.
2. Run:
bgp { as-number-plain | as-number-dot }
The BGP view is displayed.
3. Run:
ipv6-family [ unicast ]
The BGP IPv6 unicast address family view is displayed.
4. Run:
peer { ipv4-address | ipv6-address | group-name } keep-all-routes
All route updates of the peers are kept.
After this command is run, all the route updates of the specified peer are kept regardless
of whether the filtering policies are used. When the BGP connections are soft reset,
this information can be used to generate the BGP4+ routes.
Soft Resetting a BGP4+ Connection Manually
1. Run:
refresh bgp ipv6 { all | ipv4-address | ipv6-address | group group-name |
external | internal } { export | import }
A BGP4+ connection is soft reset.
A BGP4+ connection must be soft reset in the user view.
Run the display bgp ipv6 network command to check the routes advertised through the
network command.
