Dear Forum,
My name is Yohan Gunawan from Indonesia.
I have a set up with requirement as below:
two cisco router 2621 back to back
bandwith 64kbps each
router ospf
LAN HQ=10.10.2.1/25
LAN Branch=10.1.1.1/25
HQ Branch
.241 10.1.1.240/30 .242 Link1
8801 P1 ---------------------- P1 1101
2621 2621
8802 P2 ---------------------- P2 1102
.245 10.1.1.244/30 .246 Link2
P1 & P2 is analog phone 1 & 2 with the number: 88xx @ HQ and 11xx @ branch
The requirements are (refer to the diagram):
1. Branch has 2 connection to HQ: link1 10.1.1.240/30 and link2 10.1.1.244/30
2. Routing Protocol: OSPF
3. link1 is for data; link2 for voice (say 2 channel voice)
4. upon link1 failure, data is routed through link2. Since link2 is shared by data and voice. voice channel need to be reduced to 1 channel only
I have tried RSVP to reserved 1st call, but how do I make the 2nd call (considering the way call-rsvp is configured in dial-peer)
If I reserved 2 call (as per config attached), then data will not use the bandwith as it is reserved by the voice traffic (ip rsvp bandwith 48)
I havent been able to deliver item 4 requirement with this idea (as per config I attach).
Do you have any idea how to do this. As far as I know cisco does not have a specific feature that match exactly with this requirement.
Thank you very much
Yohan
