hsrp

[admin_2]

we have a setup that needs to be running out to the internet 24/7. of course we don't have a budget for the techs to be there 24/7. 2 ISP's and 3 T1 lines. someone had suggested HSRP with 2 routers that we already have to make sure if our primary ISP goes down then the secondary goes up. Is there any drawbacks or problems with using this? We only need outbound traffic not inbound.

Thank you.

Hello,

you can use HSRP for LAN redundancy. For ISP redundancy, you can use a routing protocol such as OSPF, you could e.g. originate two conditional default routes to your ISPs, meaning that the router only advertises the default if the connection to the ISP is up.

Can you post the configuration of both routers ?

Regards,

Georg

Since you have 3T1's and 2ISP's. I suggest that you use Policy Based Routing with Route-Maps (conditional Statements) or even floating static routes for that matter.

whatever you do, be secure but try to keep it as simple as possible.
