Syntax ADD PIM INTerface=interface [DRPriority=0..4294967295]
[ELectby={DRPriority|IPaddress}]
[HEllointerval={10..15000|DEFault|65535}] [MODe={Dense|
Sparse}] [SRCapable={Yes|No}]
where interface is an interface name formed by concatenating a Layer 2
interface type, an interface instance, and optionally a hyphen followed by a
logical interface number from 0 to 15. If a logical interface is not specified, 0 is
assumed.
Description This command adds the specified IP interface to the PIM interface list so that
PIM multicast routing can operate on this interface. Valid interfaces are:
To see a list of current interfaces, use the show interface command. Note that
multihomed interfaces must specify the logical interface number (e.g. ppp1-1).
The drpriority parameter specifies the preference for the switch to become the
designated router (DR) on this interface when electby=drpriority. A higher
value indicates a greater preference. The default is 1.
Note that for compatibility with previous versions, a DR priority of 65535 is
treated as electby=ipaddress if electby has not been specified. If
electby=drpriority is specified and drpriority=65535, then the DR priority is
set to 65535.
The electby parameter determines how the switch elects the designated router
for this interface. If drpriority is specified, the interface transmits its DR
priority in its hello messages, which allows DR election by priority. If
ipaddress is specified, the switch does not transmit its DR priority, which
causes election by IP address. The default is drpriority. Note that a switch with
electby=drpriority may still elect by IP address when it does not receive DR
priority in any one of its neighbours’ Hello messages. Election by DR priority is
possible only when all routers on the interface supply their DR priority.
The hellointerval parameter specifies the interval at which the switch sends
Hello messages from this interface. Setting the hellointerval parameter to
65535 results in a Hello message being sent with a hold time of 65535, which
means “infinity”. A router receiving this switch’s Hello never expires this
switch as a PIM neighbour. This can be useful on point-to-point links. The
default is 30 seconds.
The mode parameter specifies the PIM operating mode for the interface. The
default is sparse. All interfaces should have the same mode setting unless the
switch is a Multicast Border Router.
The srcapable parameter indicates whether this interface originates or
processes State Refresh messages. The default is no. This parameter applies to
dense mode interfaces.
Examples To add interface vlan2 to the PIM-SM interface list, with a priority of 3 to
become the designated router for the subnetwork, use the command:
add pim int=vlan2 drp=3
