Configuring The Interval For Sending The Same Update; Allowing Establishment Of Ebgp Session To An Indirectly Connected Peer Or Peer Group - HP MSR Series Configuration Manual

Step
3. Configure BGP keepalive interval
and holdtime.

Configuring the interval for sending the same update

A BGP router sends an update message to its peers when a route is changed. If the route changes
frequently, the BGP router sends a large number of updates for the route, which can cause route flaps.
This task allows you to configure the interval for sending the same update to a peer or peer group,
avoiding frequent update sending and route flaps.
To configure the interval for sending the same update to a peer or peer group:
Step
1. Enter system view.
2. Enter BGP view or BGP-VPN
instance view.
3. Configure the interval for
sending the same update to a
peer or peer group.
Allowing establishment of EBGP session to an indirectly
connected peer or peer group
Direct physical links must be available between EBGP peers. If not, use the peer ebgp-max-hop
command to establish an EBGP session over multiple hops between two peers.
To allow establishment of EBGP session to an indirectly connected peer or peer group:
Step
1. Enter system view.
