Dear All,
We want to setup WAN network with one Central Location and 19 Remote location in a star topology.
Central site router config:-1) cisco 3745 router
2) 1 portChannelized E1/T1 card for leased line to remote locations.
3) NM-HDV-E1-30 digital voice trunk module.
4) NM-4B-S/T card for ISDN dial backup.
Remote Site router config for 5 Locations :-1) cisco 1751-v router
2)WIC-2A/S for lease,WIC-1B-S/T for ISDN backup
3)VIC-2FXS
Remote site router config for remaining 14 Locations :- 1) cisco 1751-v router
2)WIC-2A/S for lease
3)VIC-2FXS for VOIP
Idea is to form a WAN data and voice network to run SAP application.
Primary media for all location will be Lease line.
ISDN backup will be used only at 5 locations as backup media.
Central location will have a PBX connected back to back to E1 network module (NM-HDV-E1-30) to support incoming voice calls from remote locations.
Posting the sample config for central location and one remote location
kindly verify whether this will work or any change is required.
Any suggestions regarding which routing protocol to be used or any other configuration related suggestions is welcomed.
Thanks
