Configure the MSDP Peer Keep Alive Messages

Configure keep alive messages to adjust the interval in seconds at which an MSDP peer sends keep alive messages (default is 60 seconds) and the interval at which the MSDP peer waits for keep alive messages from other peers before it declares them down (default is 75 seconds).

Note

In a peer relationship, the keep alive interval configured on one peer must be at least 1 second less than the hold time configured on the other side of the peer relationship. This is not applicable when the hold time is set to 0 seconds.

Procedure

Enter either Global Configuration mode or VRF Router Configuration mode for a specific VRF context:

enable

configure terminal

Optional: router vrf WORD<1-16>
Configure the MSDP peer keep alive interval:

ip msdp keepalive {A.B.C.D} <0-21845> <0-65535>

Example

Switch:1>enable

Switch:1#configure terminal

Switch:1(config)#ip msdp keepalive 21.0.0.2 70 71

`<0-21845>`	Specifies the keep alive interval in seconds. The default is 60 seconds.
