How to achieve "ip pim passive" functionality on IOS XR

filopeter · ‎10-27-2023

In IOS/IOS XE operating system it is possible to use "ip pim passive" on an interface enabled for IP multicast. This command means that the router will not send PIM messages on the interface nor will it accept PIM messages from other devices across this interface. The device will instead consider that it is the only PIM device on the network and thus act as the DR and also as the DF for all bidir-PIM group ranges. IGMP operations are unaffected by this command.

I was not able to find similar command in IOS XR. The only way I have found so far is to use neighbor-filter command with deny all statement

!
router pim
 address-family ipv4
  interface <>
   neighbor-filter DENY-ALL
!
ipv4 access-list DENY-ALL
 10 deny ipv4 any any
!

Is there better way how to achieve "ip pim passive" functionality in IOS XR?

Best Regards,

Hello @filopeter,

As I know, there isn't a direct "ip pim passive" command in Cisco IOS XR, and using the "neighbor-filter" with a deny-all ACL is the recommended method to achieve this functionality.
