FRRRouting PIM Protocol Issue: pimreg #7119

Closed pankajgarbyal closed 1 year ago

pankajgarbyal commented 3 years ago

Hello Sir/Madam,

I am using FRRRouting Release 5.1 for PIM Protocol support in my Switch. But I find that PIM Protocol is not acknowledging the multicast packets coming towards it. When i compared the same with FRR installed in Linux PC, i found that a new interface named "pimreg" is enabled by FRR but the same is not happening in FRR of my switch. Kindly provide me help to get the pimreg interface option in my switch through FRR. also provide some information on the role of "pimreg" to run the PIM Protocol at FRR.

Describe the bug PIM Protocol not working with FRR

Where RP? Please set RP and configure msdp.MSDP peering support with: https://github.com/FRRouting/frr/pull/6725

pankajgarbyal commented 3 years ago

First, I just want to verify if pimd is joining igmp groups..but "show ip igmp groups" have no joiners in pimd of switch while i can see multicast groups joining on pimd installed on Linux pc..

Any chance you can try with a more recent release, like 7.3?

mobash-rasool commented 1 year ago

I am closing this issue since we did not hear back from the reporter and it's close to 3 years and this scenario works fine in our latest release.
