Hi,

If i understand you right, you'll need 4 serial interfaces on the HO, one for each site, and 1 serial interface at each site (Hub and spoke topology).

HTH, please rate if it does help,

Thanks, but could you please more spesific, what part should I use? and BTW do I need to upgrade the IOS also? and on HO, does CISCO 3640 can support 4 serial interfaces? ..

thanks & regards

Re: Move from F/R to E1 leased line 2Mb channel, need advise

Hi Winanjaya,

To connect your routers via leased lines, with the HO router as a Hub, you'll need a serial interface on the Hub router for each spoke, accordingly you'll need 4 serial interfaces on the HO router, the 3640 can support the 4 serial interfaces, you can use this NM-4T interface:
