Cisco CRS Series - Configuring MSDP MD5 Password Authentication

PurposeCommand or Action
(Optional) Limits which multicast data is sent in SA messages to an
MSDP peer.
ttl-threshold ttl-value
Example:
RP/0/RP0/CPU0:router(config-msdp)#
Step 5
•
Only multicast packets with an IP header TTL greater than or equal
to the ttl-value argument are sent to the MSDP peer specified by
the IP address or name.
ttl-threshold 8
•
Use this command if you want to use TTL to examine your
multicast data traffic. For example, you could limit internal traffic
to a TTL of 8. If you want other groups to go to external locations,
send those packets with a TTL greater than 8.
•
This example configures a TTL threshold of eight hops.
Exits the current configuration mode.exit
Example:
RP/0/RP0/CPU0:router(config-msdp)# exit
Step 6
Defines an IPv4 access list to be used by SA filtering.
ipv4 access-list name [sequence-number]
permit source [source-wildcard]
Step 7
•
In this example, the access list 100 permits multicast group
239.1.1.1.
Example:
RP/0/RP0/CPU0:router(config)# ipv4
•
The ipv4 access-list command is required if the keyword list is
configured for SA filtering in Step 3, on page 125.
access-list 100 20 permit 239.1.1.1
0.0.0.0
