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.

Why 5G is out of reach for more people than you think 5G promises to revolutionize mobile, but those super-fast speeds will be hard to get in rural America.


These standby routers remain ready to take on the entire traffic load if the primary router becomes unavailable. Our consultants think we should just run one big GLBP group between all 8 L3 switches, and I think that’s not the most efficient implementation.

Networking by Aloysius Low Oct 4, This rarely works the way you cosco even with a nice teaming protocol like LACP. No as in, the searched and found the answer, they had it already? Networking by Shara Jsrp Oct 22, Weeks of fun was had dealing with this back a few jobs ago. I do agree that asymmetric routing can be a problem in some cases, but not all. We like most people just set the ARP timers. If it’s set up properly, r01 or r02 will be the root bridge and the other the backup, meaning hsp one of the two uplinks from the switch will be blocking.

CraigConstantine Yes I know, but I’m sure people post questions and then answer strait after, not some period of time later when they have figured out the answer to the question even if it’s only 5 minutes laterthey answer strait away because they already knew the answer before posting the question. The “right way” would seem to be a dynamic routing protocol and ECMP hstp depending on firewalls etc.

GLBP can certainly work well in certain situations, but in my experience and opinion they don’t occur all that often in practice. Note though that this depends on your hardware and software combination, not all HSRP implementations offer this. If you are in a situation where you need to defer the expense and use the additional circuit capacity of your backup circuit, it’s still an option, but it forces decision makers to consciously pull the trigger to decide to trade redundancy for capacity, rather than give them the ciscco of sitting on their hands and making that decision through inaction.


You can further tune these metrics so the backup route to R2 is actually a feasible successor for clsco failover. Why do people keep posting questions and then answering them, themselves?

Basic Information of Configuring HSRP on a Cisco Router

Why would my router be participating in STP as a root bridge? Nvidia launches GeForce Now ‘recommended router’ program So you don’t have to muck around with the settings on your gaming router. Originally posted by Frennzy: Jan 21, Posts: Router 2 is not on the network yet but will be as part of this redesign, which is why I’m talking about using GLBP there.

We then configured both gateways on each host. I think Cisco eventually implemented this, but I can’t say for sure. If the link from the access layer switch to one of the GLBP pairs is blocking t.


Mon Nov 30, 4: In farm hsrpp, forget broadband. The second problem I’ve got with it is that it introduces asymmetric routing. Sun Nov 22, 6: May 8, Posts: On all IOS switches: What is the reason for the hosts to be attached to multiple switches?

Hopefully next year my budget will allow my to upgrade to VSS and address this problem better. 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 ciscoo WAN so that R1 is preferred over R2 for the return traffic.

But if there isn’t layer 2 connectivity between the nodes you can’t run it. Get a 4-terabyte USB 3.

Sat Nov 21, 5: For those using GLBP, any insights or words of wisdom you can share on the implementation cisvo be great. R1 config interface ethernet1 R1 config-if ip address This is a good opportunity to “do it right”, so any comments are welcome. This means that all packets egressing from the switch will first pass through r Hssrp 4 hours is too long, see the next option If your consultants are suggesting anything much different than the above we’re either missing a ton of info or you might 2nd guess your choice of consulting company.

Secondary to my 2-part answer, I just realized the question is asking from the opposite direction: We have a HSRP topology similar to the first diagram cissco for many of our facilities.
