Parameters
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command displays detailed status information for MSDP peers on the public network.
peer-address: Specifies an MSDP peer by its address. If you do not specify an MSDP peer, this command displays detailed status information for all MSDP peers.
Examples
# Display detailed status information for MSDP peer 20.20.20.20 on the public network.

Table 52: Command output
Field | Description |
---|---|
MSDP peer | MSDP peer address. |
AS | Number of the AS where the MSDP peer is located. If the system could not obtain the AS number, this field displays a question mark (?). |
State | MSDP peer status:
|
Up/Down time | Length of time since the MSDP peering connection was established or torn down. |
Resets | MSDP peering connection reset times. |
Connection interface | Interface and IP address used for setting up a TCP connection with the remote MSDP peer. |
Received/sent messages | Number of SA messages sent and received through this connection. |
Discarded input messages | Number of discarded incoming messages. |
Discarded output messages | Number of discarded outgoing messages. |
Elapsed time since last connection or counters clear | Elapsed time since the MSDP peer information was last cleared. |
Mesh group peer joined | Mesh group that the MSDP peer has joined. This field is not displayed if the MSDP peer does not join a mesh group. |
Last disconnect reason | Reason why last MSDP peering connection was torn down. If the connection is not terminated, this field does not display a value.

Information about (Source, Group)-based SA filtering policy | SA message filtering list information:
|
Information about SA-Requests | SA request information:
|
Minimum TTL to forward SA with encapsulated data | Lower TTL threshold for the multicast packets encapsulated in SA messages. |
SAs learned from this peer | Number of cached (S, G) entries learned from the specified MSDP peer. |
SA-cache maximum for the peer | Maximum number of (S, G) entries learned from the specified MSDP peer that the device can cache. |
Input queue size | Data size cached in the input queue. |
Output queue size | Data size cached in the output queue. |
