debug
ip
msdp
[peer-address |
peer-name] [detail] [routes]
Use this command to debug MSDP activity.
Use the optional
peer-address or
peer-name argument to specify for which peer debug events are logged.
The following is sample output from the
debug
ip
msdp command:
Example:
Device# debug ip msdp
MSDP debugging is on
Device#

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:
Example:
Device# show ip msdp sa-cache
MSDP Source-Active Cache - 8 entries

Step 7
|
show
ip
msdp
summary
Use this command to display MSDP peer status.
The following is sample output from the
show
ip
msdp
summary command:
Example:
Device# show ip msdp summary
MSDP Peer Status Summary
