Chamara,
Are you PATing to hide your users behind a different IP address on
each 877? Is most of your traffic outbound? Is the switch Layer 2 or
Layer 3?
You have a number of options given that you are PATing for mostly
outbound traffic. To name a couple:
1) If you are using a Layer 2 switch, you might be able to take your
two VLANs and mash them into one depending upon your IP usage and then
use GLBP to load balance your PCs across a virtual next hop address.
2) If you are using a Layer 3 switch, you could use RIP, OSPF, or
EIGRP equal cost route load balancing between the switch and the
routers.
I'm not sure what the 877 does or does not support, however. I would
suggest taking a look at your IOS version on Cisco's Feature
Navigator.
