show bgp routes

For IPv4 and IPv6 address families:

show bgp routes {address-family [ipv4-unicast | ipv4-multicast |ipv6-unicast | ipv6-multicast | ipv4-vxlan]} {detail} [ipv4-vxlan | all | as-path path-expression | community [no-advertise | no-export | no-export-subconfed | number community_number | autonomous-system-idbgp-community] | network [any/netMaskLen | networkPrefixFilter] {exact}]

For the VPNv4 address family:

show bgp routes address-family vpnv4 {detail} [all | as-path path-expression | community [no-advertise | no-export | no-export-subconfed | number community-number |autonomous-system-idbgp-community] |rd rd network [any/netMaskLen |networkPrefixFilter] {exact}]

Description

Displays the BGP (Border Gateway Protocol) route information base (RIB).

Syntax Description

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.

ipv4-vxlan Specifies an IPv4 VXLAN address family.

vpnv4

Specifies the VPNv4 address family for Layer 3 VPN support.

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.

Default

If no address family is specified, IPv4 unicast is the default.

Usage Guidelines

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.

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.

You can only execute the show for vpnv4 address family in a VR context. If you execute this command in a VRF context, the “Cannot execute command in VRF context” error is displayed.

This command applies to the current VR or VRF context.

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.

The following command displays detailed information about all BGP routes:
