Router1841 config for mpls communication

Please help me how can I config a 1841 router?!

I have a Cisco 1841 router that the fast Ethernet 0/0 is connected to g.shdsl zyxel p793h modem ( my wan mpls connection with IP 192.169.213.9  set on this port) and the another fast Ethernet 0/1 port is connected to my LAN swith with the same IP range(192.169.213.XXX) . I can't set an IP on fast ethernet0/1 because overlaps error is haven on router  also the wan network has 255.255.255.252 subnet mask and the LAN network subnet mask is 255.255.255.0

Please help me how can I config the both fast Ethernet on router

Hello Gold.godfather1 ,

First of all, You should remove the public IP from the post, there is no need to have that.

You mentionned MPLS communication in the title, who is providing you the MPLS ? Is it a MPLS-VPN ?
Haven't you received any instruction from your service provider ?


You shouldn't use the public IP (public subnet) for your LAN. Instead you should use some prive IP subnet and perform maybe some NAT.

But you need to be more clear about what you want to achieve otherwise we won't be able to help you.


Best regards.
