This command disables an address family or the route refresh capability for one or all neighbors.
| all | Specifies that the configuration applies to all neighbors in the specified address family. If no address family is specified or if an IPv4 address is specified, the configuration applies to all IPv4 neighbors. If an IPv6 address family is specified, the configuration applies to all IPv6 neighbors. |
| remoteaddr | Specifies the IPv4 or IPv6 address of a BGP neighbor. The switch uses the IP address format to determine if the address is an IPv4 or IPv6 address. |
| ipv4-unicast | Specifies the IPv4 unicast address family. |
| ipv4-multicast | Specifies an IPv4 multicast address family. |
| ipv6-unicast | Specifies the IPv6 unicast address family. |
| ipv6-multicast | Specifies an IPv6 multicast address family. |
| vpnv4 | Specifies the VPNv4 address family for Layer 3 VPN support. |
| route-refresh | Specifies ROUTE-REFRESH message capabilities. |
| ipv4-vxlan | Specifies IPv4 VXLAN capability. |
| l2vpn-evpn | Specifies L2 VPN EVPN address family. |
The following capabilities are enabled by default for IPv4 peers: IPv4 unicast, IPv4 multicast, and route refresh.
The following capabilities are enabled by default for IPv6 peers: route refresh.
This command applies to the current VR or VRF context.
Note
To inter-operate with Cisco routers for BGP graceful restart, you must enable IPv4 unicast address capability.
For an IPv6 peer, an IPv6 address family must be specified, because an IPv6 peer does not support IPv4 address families. If no address family is specified for an IPv6 peer, the default, the IPv4 unicast address family, applies and the command fails. Similarly an IPv4 peer only supports IPv4 address families and the command fails if an IPv6 address family is specified.
The following example disables the route-refresh feature for all neighbors:
disable bgp neighbor all capability route-refresh
The following example disables the VPNv4 address family for a neighbor:
disable bgp neighbor 192.168.96.235 capability vpnv4
