Dear All,
We do have two sites (LIC and 39B). one with MSFC2
and 2600 and one with RSM and 2600. .These sites are connected via T-3
and
T-1. We would like to use the T-1 as a backup in case T-3 fails .We
want
just only one segment (10.130.0.0/16 from 39Bway to go over T-1 to LIC
segment which is 130.0.0.0 this is our Back Office services that we
need
to have protected and insure that it is operational all the times
given a
sudden failure on the primary link T-3).
We want a solution to this problem by using Static Routes and
Administrative Distance.
Note: Please, be advise that the IP addresses might not be the right
one. (Those IPs we came up with are just samples.)
Another consideration is that we have to deal with bridging irb
too so would you please think at anything that we are missing
but solve
our problem.
We want to see this scenarios from another angle and to consider another
way of achieving our goal (we might need to use IP of Loop back
Interfaces on
both : RSM and MSFC ,or to use IP address of VLAN 30 on one site and VLAN
130
on the other site, also the use of access list too ) by using static
route
and administrative distance.
Also, you might want to use different IP scheme and also keep in mind
that in
LIC site (vlan 30) the Gateway is 130.0.5.1 and 39Bway (vlan 130) the GW
IP:
is 10.130.9.1 and is configured in all the workstations.
Any help or input it will be GREAT.
Thank you,
Mike P.
