hello. We're looking to implement interface (IP event) and BFD dampening. We currently have BFD being tracked by BGP as well as BGP route dampening in place :interface te1/1/1bfd interval 700 min_rx 700 multiplier 3 router bgp 65000bgp dampeningneig...

I've attached a LLD of my design. The ASRs have eBGP neighborship with WAN side. In the LAN, both ASRs and the firewall are in the same OSPF broadcast network. The L2 switch in between is a 6800 in VSS. Both ASRs learn the same customer routes from e...

Hello!We have about 4 eBGP neighborships with our customer devices and the links are often highly unstable (international submarine cable issues and the like).This causes the BGP neighborships to flap. - We're using BFD - All neighbors advertise the ...

Thanks, the values are something we can determine along with our customer. However, like you, even I couldn't get it to work in GNS3. Just wanted to ensure the configuration is correct.

Hi David, Thanks for your response. My query is mainly with respect to whether both IP event dampening & BFD dampening need to be implemented together (IMO one would be enough).And also I need help with implementing BFD dampening.

hi David,This is the doc I originally referred. It has really limited information.

Hi MHM, The Palo Alto Firewalls are in active/passive mode and only the MAC of the active firewall is learnt by the switches. When traffic from ASR1 via switch1 (upper switch) needs to reach the firewall, it will go over the VSL and then onto the fir...

Hello Joseph,As per your initial reply, it seems that being a DR or BDR does not affect convergence time. Tested this out in GNS3 with my same timers of 3 and 9. It does take 14-15 seconds for full convergence irrespective of whether firewall is DR a...
