Hi, PIM creates automatically mGRE tunnel. I've been searching for more info about this kind of automatically created tunnel of PIM but with no luck. All I can find is either about PIM or GRE. Anyone can help me and share few links to read? Is there ...

Hi, I have set up where I'm using static routing towards a VRRP IP address. Everything is working fine. My question is what will happen when these 2 VRRP routers fall out of sync (the link between them goes down). Will the static routing fails? All ...

Hi, how can i manipulate BGP routing over MPLS. I have s subnet that's advertised by one router in 2 different VRFs and received on a single VRF (some internal issue with wrong design that I can't rectify at the moment). This subnet is advertised twi...

Hi, I have a the following scenario:LAN 11 <=> R1 (VRF-1 and OSPF 1) <=> R3 LAN 12 and internal FWInternet FW <=> R1 (VRF-2 and OSPF 2) <=> R3 LAN 12 and internal FW I want the VRF-1 subnets to go the internal FW and then come back to R1 but on VRF-2...

Hi, I have a wide L2 network where VLANs are extended across many switches. I've been facing an issue with mDNS traffic flooding the entire L2 network, and due to hardware limitations, I haven't been able to completely block it. On the Catalyst 2960,...

I had exactly the same problem. After looking at the ACL, I found that I wrote wrong wildcard. 10.10.0.0 0.0.0.128 => 10.10.0.0 0.0.0.127

Thanks @Joseph W. Doherty! I work for a service provider and the network is way more complicated than what I've shared here. I try not to over complicate things when I write a post here in Cisco Community. Instead, I try to ask specific questions tha...

Thanks a million @Giuseppe Larosa for the detailed explanation! I've unfortunately never heard of NG MVPN. The link you shared is for XR IOS, does NG MVPN works on regular IOS, i.e XE ? I found for Nexus IOS but not XE.

Good question, however these links are out of my responsibly. I assume that the FW is set up as HA with L2 connection to 2 switches and then to R1 and R2. If the link between CE to R1 fails the traffic will go to R2 then to R1 as R1 will remain the p...

It's correct as you wrote, all interfaces are in the same VLAN (or bridge-domain), say VLAN 10. The L2 switches should be connected to each other, but unfortunately I don't have access them nor the FW and the customer won't share their internal set u...
