5500G EI ACL or source based routing

5500G EI ACL or source based routing

5500G EI ACL or source based routing

I have a 5500G with the EI load with two discontiguos subnets on it, .2.0/25 and .4.128/25.  I have two vlans, 2 and 4, configured in which each corresponding subnet lives.  The address for vlan 2 is .2.125 and for vlan 4 is .4.251.  The hosts on the subnets use those addresses as their default gateways.

I can route between the two subnets perfectly.  My problem is this: I want to have vlan 2 use .2.126 as its default gateway and vlan 4 use .4.254 as its default gateway.  It seems I can only set one default gateway.

Is there a way to setup ACL or source based routing?

The reason I need this is that my downstream firewall seems to be having issues with a packet going out interface 1 (the .2.126 interface) and coming back in interface 2 (the .4.254 interface).



RE: 5500G EI ACL or source based routing

I don't believe you can with that device as Policy Based Routing is not supported on the 5500 range.  The reason is that it is not possible to achieve wire speed routing using PBR, something that 3Com do not want to compromise on a switch.

The alternative is to use a lollipop router (such as a Cisco 800 series router) and use a route-map to specify the next hop, based on source address.  

The significant problems we face cannot be solved at the same level of thinking we were at when we created them
