Table 175: MSDP Configuration Details
Task
Enable MSDP on the router.
A router interested in MSDP messages, such as a rendezvous point (RP), might have to
process a large number of MSDP messages, especially source-active messages, arriving
from other routers. Because of the potential need for a router to examine, process, and
create state tables for many MSDP packets, there is a possibility of an MSDP-based DoS
attack on a router running MSDP. To minimize this possibility, you can configure the router
to limit the number of source active messages the router accepts. Also, you can configure
a threshold for applying random early discard (RED) to drop some but not all MSDP
active source messages.
To configure the MSDP active source limit on the router in NSM:
In the NSM navigation tree, select Device Manager > Devices.
1.
Click the Device Tree tab, and then double-click the device to select it.
2.
Click the Configuration tab. In the configuration tree, expand Protocols.
3.
Select Msdp.
