HSRP and GLBP

[eigrpy]

Hi As we know, the two routers could be active at the same time in GLBP, but its drawback is some kind of traffic inbound and outbound may be not go through the the same router, instead, inbound could go one router and outbound could go another router. This would be an issue in some situation. So HSRP would solve the issue. How do you think about the issue ? Thank you

Why would it be an issue ?

Bear in mind you get the same with HSRP ie. traffic may go out of the same router but it won't necessarily come back via the same router unless you are running HSRP on both sides and the same router is active.

Edit - the only time taking different paths is an issue is if you have a stateful device in the path but this is unlikely to be the case with end clients in a vlan where you are using HSRP or GLBP.

Using the host-dependent load balancing method with GLBP can keep stateful connections from breaking, while still giving the advantages of load-balancing.
