Displaying And Maintaining Msdp; Msdp Configuration Examples; Inter-As Multicast Configuration Leveraging Bgp Routes - HP 4800G Series Configuration Manual

To protect the router effectively against denial of service (DoS) attacks, you can set a limit on the
number of (S, G) entries the router can cache.
Follow these steps to configure the SA message cache:
Enter system view
Enter MSDP view
Enable the SA cache mechanism
Configure the maximum number of (S,
G) entries learned from the specified
MSDP peer that the router can cache

MSDP Configuration Examples

Inter-AS Multicast Configuration Leveraging BGP Routes

Network requirements
There are two ASs in the network, AS 100 and AS 200 respectively. OSPF is running within each
AS, and BGP is running between the two ASs.
PIM-SM 1 belongs to AS 100, while PIM-SM 2 and PIM-SM 3 belong to AS 200.
Each PIM-SM domain has zero or one multicast source and receiver. OSPF runs within each
domain to provide unicast routes.
It is required that the respective Loopback 0 of Switch B, Switch C and Switch E be configured as
the C-BSR and C-RP of the respective PIM-SM domains.
To do...
display msdp brief [ state { connect | down |
listen | shutdown | up } ]
display msdp peer-status [ peer-address ]
display msdp sa-cache [ group-address |
source-address | as-number ] *
display msdp sa-count [ as-number ]
reset msdp peer [ peer-address ]
reset msdp sa-cache [ group-address ]
reset msdp statistics [ peer-address ]
Use the command...
system-view
msdp
cache-sa-enable
peer peer-address
