Usage guidelines
To implement BGP session soft-reset when the local router and a peer or peer group do not support the
route refresh function, use the
peer keep-all-routes
command to save all route updates received from the
peer or peer group. After modifying the route selection policy, filter all saved routes with the new policy
to refresh the routing table. This method avoids tearing down BGP sessions.
Examples
# In BGP IPv4 unicast instance view, save all route updates from peer 1.1.1.1.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv4-family unicast
[Sysname-bgp-ipv4] peer 1.1.1.1 keep-all-routes
# In BGP-VPN IPv4 unicast instance view, save all route updates from peer 1.1.1.1.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ip vpn-instance vpn1
[Sysname-bgp-vpn1] ipv4-family unicast
[Sysname-bgp-ipv4-vpn1] peer 1.1.1.1 keep-all-routes
# In BGP IPv6 unicast instance view, save all route updates from peer 1::1.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv6-family unicast
[Sysname-bgp-ipv6] peer 1::1 keep-all-routes
