Chapter 30  MSDP Configuration

 

30-12 

After the above configuration, execute display commands in any view to display the 

running information of MSDP and to verify the effect of the configuration. 

Execute the debugging command in user view for the debugging of MSDP. 

Table 30-17 Displaying and debugging MSDP configuration 

 

 

Display the numbers of sources and 
groups of SA messages from a 
specified autonomous domain 

display msdp sa-count [ as-number ] 

Display the details of a MSDP peer 

display msdp peer-status 
[ peer-address ] 

Display the (S,G) state learnt from 
MSDP peer 

display msdp sa-cache [ group-address | 
[ 

source-address ] ] 

[ autonomous-system-number ] 

Display MSDP peer state 

Enable MSDP debugging 

debugging msdp { all | connect | event | 
packet | source-active } 

 

Note that only after the cache-sa-enable command is executed, will the display msdp 

sa-count command have output. 

The mtracert command can be used in any view to trace the network path of multicast 

data from multicast source to destination receiver and locate faults. 

Table 30-18 Tracing the transmission path of SA messages on the network 

Trace the transmission 
path of SA messages on 
the network 

msdp-tracert  {  source-address  } { group-address } 
{ rp-address } [ max-hops max-hops ] [ next-hop-info ] 
[ sa-info ] [ peer-info ] [ skip-hops skip-hops ] 

 

Locating information loss and reducing configuration faults can be realized by tracing 

the network path of the specified (S, G, RP) entries. After the transmission path of SA 

messages is determined, the overflow of SA messages can be avoided by the correct 

configuration.
