Verifying Bgp Nsf; Verifying Ospf Nsf - Cisco RSP2 - Route Switch Processor 2 Installation And Configuration Manual

Redundancy mode: sso(7)
CEF NSF: enabled/running

Verifying BGP NSF

To verify NSF for BGP, you must check that the graceful restart function is configured on the
SSO-enabled networking device and on the neighbor devices. Perform the following steps:
Verify that "bgp graceful-restart" appears in the BGP configuration of the SSO-enabled router by
Step 1
entering the show running-config command:
Router# show running-config
router bgp 120
bgp graceful-restart
neighbor 10.2.2.2 remote-as 300
Repeat Step 1 on each of the BGP neighbors.
Step 2
Step 3 On the SSO device and the neighbor device, verify that the graceful restart function is shown as both
advertised and received, and confirm the address families that have the graceful restart capability. If no
address families are listed, then BGP NSF also will not occur:
router#show ip bgp neighbors x.x.x.x
BGP neighbor is 192.168.2.2,
BGP version 4, remote router ID 192.168.2.2
BGP state = Established, up for 00:01:18
Last read 00:00:17, hold time is 180, keepalive interval is 60 seconds
Neighbor capabilities:
Received 1539 messages, 0 notifications, 0 in queue
Sent 1544 messages, 0 notifications, 0 in queue
Default minimum time between advertisement runs is 30 second

Verifying OSPF NSF

To verify NSF for OSPF, you must check that the NSF function is configured on the SSO-enabled
networking device. Perform the following steps:
Verify that 'nsf' appears in the OSPF configuration of the SSO-enabled device by entering the show
Step 1
running-config command:
Router# show running-config
router ospf 120

network 192.168.30.0 0.0.0.255 area 1
network 192.168.40.0 0.0.0.255 area 2
Use the show ip ospf command to verify that NSF is enabled on the device:
Step 2
router> show ip ospf
