Hi

Seek expert getlemen's help in finding out a basic cisco router with 4 gig eth ports. Therez a requirement of LAN to Lan routing. The router should be IP SLA compliant. Unfortunately could not get much help from "Solution Finder" on cisco site

Thanks

Hitesh

Hello Hitesh,

look for multilayer switches they can support IP SLA in recent IOS images and are the right devices for inter-vlan routing

to find a router that really supports 4 GE ports you should go to an ASR 1000 but it is much more expensive then a multilayer switch.

see 3560

Hope to help

It depends what you mean by "Lan to Lan routing".

If you simply mean inter-vlan routing within a LAN then Giuseppe is spot on with his advice, a L3 switch is the way to go. But i'm not entirely sure why you would need IP SLA simply for inter-vlan routing.

If you mean LAN to LAN across a WAN then you may well need to look at a router. Because you are looking for 4 gigabit interfaces it does suggest that either -

a) you are just doing inter-vlan routing

or

b) your WAN connections present as ethernet

Bear in mind that routers offer many more capabilites such as a more fully featured QOS set, NAT (only the 6500 switch can do NAT) etc.. But as Giuseppe says a router with 4 gigabit interfaces is expensive. Depending on what you need the interfaces for however you may be able to use an ISR router such as a 2800 with an etherswitch module which would give you the additional ports.

Without knowing more it's difficult to be precise.

A router with 4 GigEthernet?   I presume you want copper?  Hmmmm ...

It'll have to be a Cisco 3825 (2 GE) plus two HWIC-1GE-SFP + two GLC-TX.

I wouldn't call a 3800 router "basic".
