Configuring manual soft-reset
If a BGP peer does not support route-refresh, you must save updates from the peer on the local router by
using the peer keep-all-routes command, and use the refresh bgp command to refresh the BGP routing
table.
If the BGP peer does not support route-refresh and the peer keep-all-routes command is not configured
on the local end, you must decide whether to manually disconnect the session with the peer to learn
routes again according to the impact of the new policy.
To save all route updates from a peer or peer group:

Disabling BGP routing policies from automatically
taking effect
During BGP network optimization or upgrade, each change of BGP routing policies triggers route
refreshing, which burdens BGP routers and the network.
This task disables the policies from automatically taking effect. After modifying all policies, execute the
refresh bgp or reset bgp command to make the new polices take effect.
The following shows BGP routing policies:
