Configuring Echo Response for N9 Interface

The echo response in a GTP-U service provides the availability of peer UPF.

The following is a sample echo response configuration for the N9 interface in hUPF:

gtpu-service n9-ingress
   echo-interval 60
   echo-retransmission-timeout 1
   bind ipv4-address 60.60.41.5 bearer-type all
   exit

The following is a sample echo response configuration for the N9 interface in vUPF:

gtpu-service n9-egress
   echo-interval 60
   echo-retransmission-timeout 1
   bind ipv4-address 60.60.42.5 bearer-type all
   exit
