Cisco 3550 Multi WAN and many vlans
Hello and happy Holidays all.
I have a Cisco 3550 switch I am setting up but having some issues with.
We have two different WAN connections from different providers.
We are using many internal vLANs.
Both fa 0/2 and 0/3 are drops from isp’s, I addressed vlan 1 with the assigned subnet from isp 1 and vlan 2 with subnet addressing from isp2. I want fa 0/2 to be assigned to the isp2 / vlan2, and fa 0/3 to use isp1/vlan1. Then assign other vlan’s to each of these trunked. I enabled ip routing and input 2 routes, one to each of the isp provided gateways.
What else needs to be assigned or configured for this? After setting up the trunks I am having intermittent pings and remote access to the IOS is slow and hangs randomly.
I am also trying to setup ip helper address.
I have a dhcp server on vlan 6 to assign addresses into other vlans, through ip helper address I assume. Would I assign the helper address onto each desired vlan interface or eth interfaces and if so Is that all that needs to be done for helper address?
Thanks for any help!

If I take fa0/2 and fa0/3 off switchport mode trunk how can I assign the 'ISP' Vlans to these ports? Right now I can ping the vlan1 management address from outside the network but not the other isp link vlan 2.
