I have central 3845 router which have 2 default fastethernet port. remote branch location has 800 router. I have 5 ISP for connect different branch. in 3845 one port is conect data server and rest only single port. 5 isp connect in 2950 switch and 3845 router is connect switch.
all remote branch need to also IPSEC.
For this I need to do.
1. Router interface subinterface.
2. switch port need Trunk as all VLAn ISP connect router
3. site to site IPSEC and implement cryptomap in subinterface.
IF my guess is right then how i configure subinterface and trunk in switch. can any one provide any link or sample configuration seperate router for subinterface and VLAN& Trunk for switch.
You cannnot configure sub-interfaces on a switch. For this you have to create sub-interfaces on the router and trunk on the switch. All the switch vlans will have its gateway on the 3845 sub-interfaces which inturn will be doing inter-vlan routing.
