The system view is displayed.
2. Run:
bgp as-number
The BGP view is displayed.
3. Run:
peer { ipv4-address | ipv6-address | group-name } capability-advertise
{ route-refresh | 4-byte-as }
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+ switchs, the local switch
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 switch again.
In this way, the BGP4+ routing table is updated dynamically and the new policies are
applied without interrupting the BGP4+ connections.
l Keeping All Route Updates of Peers
Do as follows on the BGP4+ switch:
1. Run:
system-view
The system view is displayed.
2. Run:
bgp as-number
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.
l Soft Resetting a BGP4+ Connection Manually
Do as follows on the BGP4+ switch:
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.
