2851 Router Redundancy

Hi,

I'm thinking of buying the two 2851 routers, each servcing a separate ISP link. As far as I understand the specs, the 2851 comes with two dual gig ethernet ports. Now on each router I need one link for the ISP and another link for the internal connection.

My question is if I need to do redundancy do I need to run a link between the two routers, if I do then should I purchase an four port HWIC port module? Additionally I don't know anything about redundacy except a bit about hsrp, would hsrp be suitable for this scenario?

Thanks in advance

Dan

Re: 2851 Router Redundancy

Hi,

you do not need to run a link between two routers to achieve redundancy.

Both routers will connect to a LAN switch and you can run HSRP on routers to build redundancy.

please see below links for more information.

hi DAN,

you can have GLBP as well as HSRP for redundancy purpose... you can get more information from the cisco website and you dont need to have connection between two router... you can use ethernet switch to connect both the router...

here is the link for GLBP:http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t15/ft_glbp.htm

rate this post if it helps
