Configuring MSDP
MSDP: 224.150.44.254: Peer RPF check passed for 172.31.3.78, used EMBGP peer
MSDP: 224.150.44.250: Forward 32-byte SA to peer
Step 3 debug ip msdp resets
Use this command to debug MSDP peer reset reasons.
Example:
Device# debug ip msdp resets
Step 4
show ip msdp count [as-number]
Use this command to display the number of sources and groups originated in MSDP SA messages and the number of
SA messages from an MSDP peer in the SA cache. The ip msdp cache-sa-state command must be configured for this
command to produce any output.
The following is sample output from the show ip msdp countcommand:
Example:
Device# show ip msdp count
SA State per Peer Counters, <Peer>: <# SA learned>
192.168.4.4: 8
SA State per ASN Counters, <asn>: <# sources>/<# groups>
Total entries: 8
?: 8/8
Step 5 show ip msdp peer [peer-address | peer-name]
Use this command to display detailed information about MSDP peers.
Use the optional peer-address or peer-name argument to display information about a particular peer.
The following is sample output from the show ip msdp peercommand:
Example:
Device# show ip msdp peer 192.168.4.4
MSDP Peer 192.168.4.4 (?), AS 64512 (configured AS)
Connection status:
State: Up, Resets: 0, Connection source: Loopback0 (2.2.2.2)
Uptime(Downtime): 00:07:55, Messages sent/received: 8/18
Output messages discarded: 0
Connection and counters cleared 00:08:55 ago
SA Filtering:
Input (S,G) filter: none, route-map: none
Input RP filter: none, route-map: none
Output (S,G) filter: none, route-map: none
Output RP filter: none, route-map: none
SA-Requests:
Input filter: none
Peer ttl threshold: 0
SAs learned from this peer: 8
Input queue size: 0, Output queue size: 0
MD5 signature protection on MSDP TCP connection: not enabled
Step 6 show ip msdp sa-cache [group-address | source-address | group-name | source-name] [as-number]
Use this command to display the (S, G) state learned from MSDP peers.
The following is sample output from the show ip msdp sa-cachecommand:
