Virtual Private Routed Network Services
7750 SR OS Services Guide Page 1049
Description This command specifies the import route policy to be used for determining which routes are accepted
from peers. Route policies are configured in the config>router>policy-options context.
When an import policy is not specified, BGP routes are accepted by default.
The no form of the command removes the policy association from the IGMP instance.
Default no import join-policy
no import register-policy
Parameters join-policy — Use this command to filter PIM join messages which prevents unwanted multicast
streams from traversing the network.
register-policy — This keyword filters register messages. PIM register filters prevent register
messages from being processed by the RP. This filter can only be defined on an RP. When a
match is found, the RP immediately sends back a register-stop message.
policy-name — The route policy name. Allowed values are any string up to 32 characters long
composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $,
spaces, etc.), the entire string must be enclosed within double quotes. Route policies are
configured in the config>router>policy-options context.
interface
Syntax [no] interface ip-int-name
Context config>service>vprn>pim
Description This command enables PIM on an interface and enables the context to configure interface-specific
parameters.
By default interfaces are activated in PIM based on the apply-to command, and do not have to be
configured on an individual basis unless the default values must be changed.
The no form of the command deletes the PIM interface configuration for this interface. If the apply-
to command parameter is configured, then the no interface form must be saved in the configuration
to avoid automatic (re)creation after the next apply-to is executed as part of a reboot.
The shutdown command can be used to disable an interface without removing the configuration for
the interface.
Default Interfaces are activated in PIM based on the apply-to command.
Parameters ip-int-name — Specify the interface name. If the string contains special characters (#, $, spaces, etc.),
the entire string must be enclosed within double quotes.
bfd-enable
Syntax [no] bfd-enable
Context config>service>vprn>pim>interface
Description This command enables the use of bi-directional forwarding (BFD) to control the state of the
associated protocol interface. By enabling BFD on a given protocol interface, the state of the
