Hi there   I need some help with a company merger type scenario.   I have two sites: A and B. Site A runs OSPFv2 while site B runs EIGRPv6.    The topology of the main routers is quite basic:   Site A R1 <---> Site B R1.   Both of the main routers are 1841 models and dual stacked for basic connectivity.   I need to redistribute routes between these two routers so that branch routers connected to them can obtain routes of the other sites using only their respective routing protocol. There is the option of using a L3 switch between the two main routers, but would like to attempt with just the two main routers first.   After some sample router configurations for this scenario.     ...

Hello,   I am creating a lab network that has NAT and an IPsec tunnel.   Since implementing NAT both on a packet tracer activity and physical equipment, I have encountered issues with communication over the tunnel. Prior to applying NAT, I was able to ping the opposite end of the tunnel and communicate between client machines. Although the tunnel is up, I am unable to get communication though it. I have tried several iterations and troubleshooting steps, yet the reason why it doesn't work as expected currently remains a mystery to me.   I have attached a topology of the network with router configurations for inspection (the public IP addresses are randomly selected). Any assistance would be greatly appreciated.   Cheers, Az   ... View more

Hi all,   I am setting up a lab and need some help.    My environment consists of two sites. Site A and B. Each site has vlans 10, 20, 30, 40, 50 and so forth, but each respective vlan on each site has a unique subnet. That is vlan10 on site A has a subnet of 192.168.1.0 and vlan10 at site B has subnet 192.168.2.0. Each LAN is connected to an 1841 router: RA and RC which are subsequently connected via another router RB   I understand setting up dhcp pools on RA and dhcp helper-address on RB and RC, but what I would like to do is set RA to serve dhcp addresses for both sites, but have RA serve both subnets of vlan10 at each respective site. Is this possible to use same vlan names on each sites to serve different subnets or would I need to for example assign unique  vlans for both sites. I.e. vlan10 on site A subnet and vlan 20 to subnet found at site B?    Cheers Az   ... View more
