This command displays the VPNv4 address information from the BGP table. If an optional VRF is specified, the address information for communities within that VRF instance are displayed.
| Format | show ip bgp vpnv4 {all | rd route-distinguisher | vrf vrf-name} [ip-prefix/length] |
| Mode | Privileged EXEC |
| Parameter | Description |
|---|---|
| all | Displays the complete VPNv4 database. |
| rd route- distinguisher | Displays NLRI prefixes that match the named route distinguisher. |
| vrf vrf-name | Displays NLRI prefixes associated with the communities within the named VRF instance. |
| ip-prefix/length | IP address (in dotted decimal format) and the length of the mask (0 to 32). The slash (/) mark must be included. |
The command outputs the following information, depending on the selected parameters.
| Field | Description |
|---|---|
| BGP table version | Each time phase 2 of the BGP decision process runs to select new BGP routes, this number is incremented. |
| Status codes |
One of the following:
|
| Route Distinguisher | The RD associated with the VRF. |
| Network | Destination prefix |
| Next Hop | The route's BGP next hop. |
| Metric | BGP metric. |
| LocPrf | The local preference. |
| Path | The AS path per route. |
| Prefix/Prefix Length | The destination prefix and prefix length. |
| Generation ID | The version of the BGP routing table when this route last changed. |
| Forwarding | if this BGP route is used for forwarding. |
| Advertised To Update Groups | The outbound update groups to which this route is advertised. |
| Local Preference | The local preference, either as received from the peer or as set according to local policy. |
| AS Path | The AS Path. This form of the command displays AS Paths as long as allowed by bgp maxas-limit. |
| Origin | Value of the ORIGIN attribute. |
| Metric | Value of the MED attribute, if included. |
| Type | If the path is received from an internal or external peer. |
| IGP Cost | The interior gateway cost (e.g., OSPF cost) to the BGP NEXT HOP |
| Peer (Peer ID) | The IP address of the peer that sent this route, and its router ID. |
| BGP Next Hop | The BGP NEXT HOP attribute. |
| Atomic Aggregate | If the ATOMIC AGGEGATE attribute is attached to the path. |
| Aggregator | The AS number and router ID of the speaker that aggregated the route. |
| Communities | The BGP communities attached to the path. |
| Originator | If the ORIGINATOR attribute is attached to the path, the value of this attribute. |
| Cluster List | If the CLUSTER_LIST attribute is attached to the path, the sequence of cluster IDs in the cluster list. |
| Extended Community | Route target value associated with the specified route. |
Example: The following example shows all available VPNv4 information in a BGP routing table:
(Routing) # show ip bgp vpnv4 all BGP table version is 5, local router ID is 20.1.1.1 Status codes: s suppressed, * valid, > best, i - internal Origin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Path Route Distinguisher : 1:10 (for VRF red) *> 172.20.1.0/24 100.10.1.1 10 100 20 10 i *> 24.95.16.0/24 100.10.1.1 10 100 20 10 i *> 24.14.8.0/24 100.10.1.1 10 100 20 10 i Route Distinguisher : 2:20 (for VRF blue) *> 173.20.1.0/24 120.10.1.1 10 100 20 10 i *> 25.95.16.0/24 120.10.1.1 10 100 20 10 i *> 25.14.8.0/24 120.10.1.1 10 100 20 10 i Route Distinguisher : 3:30 (for VRF yellow) *> 174.20.1.0/24 130.10.1.1 10 100 20 10 i *> 26.95.16.0/24 130.10.1.1 10 100 20 10 i *> 26.14.8.0/24 130.10.1.1 10 100 20 10 i
Example: The following example shows VPNv4 routing entries for VRF named red:
(Routing) # show ip bgp vpnv4 vrf red BGP table version is 5, local router ID is 20.1.1.1 Status codes: s suppressed, * valid, > best, i - internal Origin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Path Route Distinguisher : 1:10 (for VRF red) *> 172.20.1.0/24 100.10.1.1 10 100 20 10 i *> 24.95.16.0/24 100.10.1.1 10 100 20 10 i *> 24.14.8.0/24 100.10.1.1 10 100 20 10 i
Example: The following example shows the attributes for network 172.20.1.0 that include multi-paths and best path Use like any of the below formats):
(Routing) # show ip bgp vpnv4 vrf red 172.20.1.0 255.255.255.0
