Re: [j-nsp] Unable to ping all NE when MAC are learned in Bridge group

The NE have the correct ARP address of the MX5, the MX5 on the other hand does not have an ARP entry. It does learn a MAC from the NE in the bridge domain. for what ever reason the RI is unable to put the two together. For some reason the link between the Bridge and Routing Instance is

[j-nsp] Unable to ping all NE when MAC are learned in Bridge group

Hey Guys, We are migrating some NE to new MX-5 LER. I have started with moving mgmt to an IRB, IRB is in the bridge domain and in the routing instance. When cut over about half the NE are no longer accessible. When the NE are cut back to old default GW (resides on a c7609 within a RI) and

Re: [j-nsp] Unable to ping all NE when MAC are learned in Bridge group

gARP is not reliable and Your NE devices' ARP cache still contains old MAC from old default GW. You have to revisit them one by one and clear their arp caches, or change IRB MAC to that of old default GW' MAC. HTH Thanks Alex - Original Message - From: Jason Fortier

I have tried clearing arp for most of the devices, I have also moved the same config to MX480 PE, All NE become reachable. Below is a simple network layout. NE-MX5-1--MX5-2MX480C7609--MGMTNETWORK When MX5-1 becomes a PE some of the NE be come unreachable. One thing of note it
