Cisco 871 - can you create fast ethernet subinterfaces?

Unanswered Question
Apr 8th, 2009

I need to route two /25 subnets over the WAN. I'll have a 2950 connected to the 871 using native VLAN1 of course as well as one more additional VLAN. Can subinterfaces be created on the LAN interfaces on the 871, or must I "go up" to either an 1841 or 2800 series?

I have this problem too.

You can create another VLAN interface and use a trunk to the 871.

I.E:

interface vlan 1

ip address 10.1.1.1 255.255.255.128

interface vlan 2

ip address 10.1.1.129 255.255.255.128

Make sure to go into the vlan database and create the VLAN and you should be fine.
