For IPv4 and IPv6 address families:
show bgp {neighbor} remoteaddr {address-family [ipv4-unicast | ipv4-multicast |ipv6-unicast | ipv6-multicast | ipv4-vxlan]} [accepted-routes | received-routes | rejected-routes | transmitted-routes] {detail} [all | as-path path-expression | community [no-advertise | no-export | no-export-subconfed | number community_number | autonomous-system-id : bgp-community] | network [any/netMaskLen | networkPrefixFilter] {exact}]For the VPNv4 address family:
show bgp {neighbor} remoteaddr address-family vpnv4 [accepted-routes | received-routes | rejected-routes | transmitted-routes] {detail} [all | as-path path-expression | community [no-advertise | no-export | no-export-subconfed | number community_number | autonomous-system-id :bgp-community] | rd rd_value network [any/netMaskLen | networkPrefixFilter] {exact}]Displays information about routes to a specified neighbor.
| remoteaddr | Specifies an IPv4 or IPv6 address that identifies a BGP (Border Gateway Protocol) neighbor. |
| ipv4-unicast | Specifies IPv4 unicast routes. |
| ipv4-multicast | Specifies IPv4 multicast routes. |
| ipv6-unicast | Specifies IPv6 unicast routes. |
| ipv6-multicast | Specifies IPv6 multicast routes. |
| ipv4-vxlan | Specifies IPv4 VXLAN routes. |
| vpnv4 | Specifies VPNv4 routes. |
| accepted-routes | Specifies that only accepted routes are displayed. |
| received-routes | Specifies that only received routes are displayed. |
| rejected-routes | Specifies that only rejected routes are displayed. |
| transmitted-routes | Specifies that only transmitted routes are displayed. |
| detail | Specifies to display the information in detailed format. |
| all | Specifies all routes. |
| path-expression | Display routes that match the specified AA path expression. |
| no-advertise | Specifies the no-advertise community attribute. |
| no-export | Specifies the no-export community attribute. |
| no-export-subconfed | Specifies the no-export-subconfed community attribute. |
| community_number | Specifies a community number. |
| autonomous-system-id | Specifies an autonomous system ID (0-65535). |
| bgp-community | Specifies the BGP community number. |
| rd | Specifies the Route Distinquisher (RD) value for the Layer 3 VPN routes for which you want to clear flap statistics. |
| any | Specifies all routes with a given or larger mask length. |
| netMaskLen | Specifies a IPv4 or IPv6 subnet mask length (number of bits). |
| networkPrefixFilter | Specifies an IPv4 or IPv6 address and netmask. |
| exact | Specifies an exact match with the IP address and subnet mask. |
If no address family is specified, IPv4 unicast is the default.
show bgp neighbor now supports v6 unicast and multicast and vpnv4 address families. This command applies to the current VR or VRF context.
Note
If this command displays Bad Source Address, the BGP neighbor IP address is unavailable. Possible causes for this condition include a deleted or unconfigured VLAN (Virtual LAN) or IP address.
The option network any / netMaskLen displays all BGP routes whose mask length is equal to or greater than maskLength, irrespective of their network address.
The option network any / netMaskLen exact displays all BGP routes whose mask length is exactly equal to maskLength, irrespective of their network address.
If you do not specify an address family, this command applies to the IPv4 unicast address family. To apply this command to an address family other than the IPv4 unicast address family, you must specify the address family.
Note
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 address-family, i.e. IPv4 unicast is assumed and hence no address-family information appears. Similarly an IPv4 peer only supports IPv4 address families and no address-family information appears if an IPv6 address family is specified.
To display Layer 3 VPN information, you must enter this command in the context of on the MPLS (Multiprotocol Label Switching)-enabled VR; it is not supported for BGP neighbors on the CE (VRF) side of the PE router.
