Seperate 2 pools of VLANs on dual 3550 HSRP/EIGRP topology ?

I have a set of VLANs for one group and another set for a second group.

I need to keep these 2 groups seperate from seeing one another while also enabling routing and HSRP within each pool across the two 3550's.

Unsure of simplier way than resorting to ACLs.

Re: Seperate 2 pools of VLANs on dual 3550 HSRP/EIGRP topology ?

You can use vlan maps for this. VLAN maps can access-control all traffic. You can apply VLAN maps on the switch to all packets that are routed into or out of a VLAN or are bridged within a VLAN. VLAN maps are used strictly for security packet filtering..With VLAN maps, forwarding of packets is permitted or denied, based on the action specified in the map.

I tried VLAN maps when it seeemed to have exhausted the switch by the following dump :

02:01:37: %SYS-2-MALLOCFAIL: Memory allocation of 1680 bytes failed from 0x1473A

0, pool I/O, alignment 0

-Process= "IP Input", ipl= 6, pid= 35

-Traceback= 184EEC 186394 1473A4 1476D0 147F50 149A58 1C0F7C 1C1250 1E8A44 1E66C

C 1E67E4 1E69E8 1A4B14

No time left. We resorted to using a third router to do one pool and the two 3550's to provide the other redundant pool.

Thanks.
