Configuring PIM and PIM6
Parameter
Designated router priority
Hello authentication mode
Hello interval
Domain border
Description
Sets the designated router (DR) priority that is
advertised in PIM hello messages on this interface.
On a multiaccess network with multiple PIM-enabled
routers, the router with the highest DR priority is
elected as the DR router. If the priorities match, the
software elects the DR with the highest IP address.
The DR originates PIM register messages for the
directly connected multicast sources and sends PIM
join messages toward the rendezvous point (RP) for
directly connected receivers. Values range from 1 to
4294967295. The default is 1.
Enables an MD5 hash authentication key, or password,
in PIM hello messages on the interface so that directly
connected neighbors can authenticate each other. The
PIM hello messages are IPsec encoded using the
Authentication Header (AH) option. You can enter
an unencrypted (cleartext) key or one of these values
followed by a space and the MD5 authentication key:
• 0—Specifies an unencrypted (cleartext) key
• 3—Specifies a 3-DES encrypted key
• 7—Specifies a Cisco Type 7 encrypted key
The authentication key can be up to 16 characters.
The default is disabled.
Note
Configures the interval at which hello messages are
sent in milliseconds. The range is from 1000 to
18724286. The default is 30000.
Note
Enables the interface to be on the border of a PIM
domain so that no bootstrap, candidate-RP, or
Auto-RP messages are sent or received on the
interface. The default is disabled.

PIM6 does not support hello
authentication.

Verified Scalability Guide for the verified
range of this parameter and associated PIM
neighbor scale.

method.
