To enable bidirectional forwarding(BFD) fast-detection on a HSRP interface, use the hsrp bfd fast-detect command in interface configuration mode. This creates a BFD session between the HSRP router and its peer, and if the session goes down while HSRP is in backup state, this will initiate a HSRP failover.

BFD Support on Cisco ASR 9000 . ... BFD And HSRP . HSRP has to learn what the physical addresses of the Active and Standby router are (from the HSRP control packets). Once one of these routers change state, it's possible that another (third) router could take over as Standby. HSRP cannot assume that the same router will come back (configured ...

Sep 12, 2019 · Symptom: The message on active HSRP can be seen received from standby running 5.2.4 hsrp[1085]: %IP-STANDBY-4-WARN_TRAFFIC_SLAVE : HSRP control packet received from <standby IP> on MGO slave group: TenGigE0_0_2_0.201 group 201 Actually the hsrp standby slave group would send continuous refresh with the source hsrp vmac, causing continuous mac move in L2 …

May 07, 2014 · Version 1 and 2 use different virtual MAC address range which can be important for OTV implementation. Also BFD support of version 2 is important for efficiently detecting failure of active HSRP router since tightening control plane timers can affect performance negatively. Many bfd implementations are supported on the data plane.

BFD (Bidirectional Forwarding Detection) is a super fast protocol that is able to detect link failures within milliseconds or even microseconds.. All (routing) protocols have some sort of mechanism to detect link failures. OSPF uses hello packets and a dead interval, EIGRP uses hello packets and a …

Jun 14, 2014 · Everything BFD I sat down to start working on BFD three weeks ago thinking I'd be done in a couple of days. ... Alternatively, HSRP BFD support can be enabled globally with: R1(config)#standby bfd all-interfaces. IOS-based VRRP doesn't appear to have BFD support at the time of this writing. I've seen some documents indicating it is supported in ...

Aug 13, 2014 · I would not turn on msec timers on those. Which version are you running? Do you have support for BFD in your HSRP configuration? That would probably help with the CPU. I'm not sure if your linecards support BFD in hardware, but it should be less stressing than protocol hello's anyway.

Nov 20, 2017 · There is multi hop BFD but it's quite limited what devices support it. You can run BFD over DMVPN as well for example. But yes, generally your SP needs to support it. BFD is good for detecting some scenarios but plan to have link down as your detection if you can so try to stay away from "bump in the wires", fiber converters and that kind of ...
