I have been asked to investigate implementing HSRP on two routers. All the information I have collected states that the HSRP commands. This document provides a sample configuration for HSRP in Cisco Series switches for Siwtch A is active state of HSRP and Switch B is in standby state. How to Configure HSRP on a Cisco Router (with GSN3 lab) these routers could be multilayer switches such as a Cisco or as well.

May 8, Posts: I neglected to include that in my answer There doesn’t even need to be HSRP, just if there are two routers it can bite you and cause even loops. There are a few limited scenarios where it could be useful, but most of the time, it’s a solution in search of a problem, as far as I’m concerned.
Here again is our two router topology, hrp the preempt command added.
Sat Nov 21, 1: To me, ECMP is the real issue here – so in addition to the above steps to limit unknown unicast flooding, you can also tune the route metrics toward the WAN so that R1 is preferred over R2 for the return traffic.
Get a 4-terabyte USB 3. In a typical topology like the one you drew the 6 distribution layer switches are the border between layer 2 and 3 where the default lives.
If your consultants are suggesting anything much different than the above we’re either missing hsrpp ton of info or you might 2nd guess your choice of consulting company. Long answer, so let me break this into two parts. Jan 26, Posts: Life in the slow lane: Would you have a suggestion on what would be considered a better topology?
This is a good opportunity to “do it right”, so any comments are welcome. Note though that this depends on your hardware and software combination, not all HSRP implementations offer this. R2 show standby Ethernet0 — Group 1 Local state is Active, priority Hellotime 3 sec, holdtime 10 sec Next hello sent in 2.
HSRP, GLBP and VRRP
Mon Nov 23, 7: If you really must load balance, do so statically using separate VLANs so you can match up default gateway configurations with STP path selection and inbound routing policies. No as in, the searched and found the answer, they had it already? No, just the two physical NICs with Intel teaming software. Environmental Parameters Min Storage Temperature.

Yet the fact remains, that writing a Q and an immediate answer is explicitly encouraged. This allows us to have each router working for us and forwarding packets to best utilize our investment in our networking equipment.
Something has to be blocking if your links between distribution switches is a trunk. I’m wondering how widely these protocols are used in the enterprise and thought a quick poll may shed some light on this. This method also is preferable if you like ciscl see PC mac entries age out of the topology quickly.
Or if you want to work it out yourself draw the packet flow if switch 6 or 8 or whatever is the default gw for a user behind sw 1 using GLBP. I find this a bit strange.
Networking by Aloysius Low Oct 4, Networking by Shara Tibken Oct 22, Don’t think we know enough about your network to make any meaningful suggestion. The higher priority will determine which router is active.
If your cusco is slow or acting weird, it’s possible someone is stealing your signal and maybe more. Yeah, I think I need to take some time and consider it a bit more Fri Nov 20, 8: Let’s say, for the purposes of this discussion, r01 is the root.
To force a particular router to be the active router xisco an HSRP group you will need to use the priority command. R1 show standby Ethernet0 — Group 1 Local state is Standby, priority Hellotime 3 sec, holdtime 10 sec Next hello sent in 0.
I’ve never been a fan of tweaking timers. I’m clearly missing something. I do think this type of thing is a superior topology, if you need higher reliability for host connections.
