Sub Interfaces on E1

Question:

I need to create WS-C3750V2-24PS-S two point to point links between two routers connected via E1.

They need to be in separate VRFs for my requirement.

Is there any way I can create that on an E1 interface? Please let me know.

Many Thanks in advance.

Answer:

I have used fractional E1 in the past for this kind of scenario.

you can use fractional E1 for this, under controller e1 you can define more then one channel-group, each of them with different timeslots associated. Two different serial interfaces are generated from this

controller e1 x/y

channel-group 1 timeslots 1-15

channel-group 2 timeslots 17-30

(check the syntax of the commands above it may be different)

this generates two serial interfaces

serx/y:1

serx/y:2

you can associated the first to VRF1 and the second to VRF2 do this on both routers and use appropriate addresses.

To be noted this provides a fixed division of resources ( 64 kbps timeslots) between the two derived serial interfaces. WS-C3750V2-48PS-S Price
