Controlling the advertising and receiving of BGP4+ routing information, which includes
the filtering of routing information and the application of the routing policies.
Soft resetting the BGP4+ connections
In the S6700, BGP4+ supports the route-refresh capability. When the policies are changed,
the system can refresh the BGP4+ routing table automatically without interrupting the
BGP4+ connections.
If there are switches that do not support route-refresh in the network, you can run the peer
keep-all-routes command to save all route refreshment locally. Then, you can run the
refresh bgp command to soft reset the BGP4+ connections manually.
