If a peer not supporting route-refresh exists in the network, you need to configure the peer
keep-all-routes command to save all routes from the peer. When the routing policy is changed, the
system will update the IPv6 BGP routing table and apply the new policy.
Prerequisites
Before configuring IPv6 BGP timers, you need to:
z Enable IPv6
z Configure IPv6 BGP basic functions
Configuring IPv6 BGP Timers
Follow these steps to configure IPv6 BGP timers:
To do… Use the command… Remarks
Enter system view system-view —
Enter BGP view bgp as-number —
Enter IPv6 address family view ipv6-family —
Specify keepalive

Configure
IPv6 BGP
timers
Configure keepalive
interval and holdtime for
an IPv6 peer/peer group
peer { ipv6-group-name |
ipv6-address } timer keepalive
keepalive hold holdtime
Optional
The keepalive interval defaults to
60 seconds, holdtime defaults to
180 seconds.
Configure the interval for sending the
same update to an IPv6 peer/peer group
peer { ipv6-group-name |
ipv6-address }
route-update-interval interval
Optional
The interval for sending the
same update to an iBGP peer or
an eBGP peer defaults to 15
seconds or 30 seconds
z Timers configured using the timer command have lower priority than timers configured using the
peer timer command.
z The holdtime interval must be at least three times the keepalive interval.
