Implementing Multicast Routing on Cisco IOS XR Software
MSDP MD5 Password Authentication
MSDP MD5 password authentication is an enhancement to support Message Digest 5 (MD5) signature
protection on a TCP connection between two Multicast Source Discovery Protocol (MSDP) peers. This feature
provides added security by protecting MSDP against the threat of spoofed TCP segments being introduced
into the TCP connection stream.
MSDP MD5 password authentication verifies each segment sent on the TCP connection between MSDP peers.
The password clear command is used to enable MD5 authentication for TCP connections between two MSDP
peers. When MD5 authentication is enabled between two MSDP peers, each segment sent on the TCP
connection between the peers is verified.
MSDP MD5 authentication must be configured with the same password on both MSDP peers to enable
Note
the connection between them. The 'password encrypted' command is used only for applying the stored
running configuration. Once you configure the MSDP MD5 authentication, you can restore the configuration
using this command.
MSDP MD5 password authentication uses an industry-standard MD5 algorithm for improved reliability and
security.
How to Implement Multicast Routing
This section contains instructions for both building a basic multicast configuration, as well as optional tasks
to help you to optimize, debug, and discover the routers in your multicast network.
Configuring PIM-SM and PIM-SSM
SUMMARY STEPS
1. configure
2. multicast-routing [address-family {ipv4 | ipv6}]
3. interface all enable
4. exit
5. Use router { igmp} for IPv4 hosts or use router { mld} for IPv6
6. version {1 | 2 | 3} for IPv4 (IGMP) hosts or version {1 | 2} for IPv6 (MLD) hosts.
7. commit
8. show pim [ipv4 | ipv6] group-map [ip-address-name] [info-source]
9. show pim [vrf vrf-name] [ipv4 | ipv6] topology [source-ip-address [group-ip-address] | entry-flag flag
| interface-flag | summary] [route-count]
