Use the no neighbor version command to return to the default version of a neighbor.
Factory Default: Only BGP version 4 is supported.
Command Mode: Router configuration.
Example: In the following example,
- The neighbor version command specifies that only BGP version 4 is accepted
- The show ip bgp neighbor command displays the setting:
router(config)#router bgp 101
router(config-router)#neighbor 121.80.100.4 remote-as 101
router(config-router)#neighbor 121.80.100.4 version 4
router(config-router)#end
router#show ip bgp neighbor 121.80.100.4
