A router 805 that is regarded as CE to MPLS/VPN. the router only support 512K bandwidth on its Interface S0,and the MPLS line bandwidth to CE is 256K,It always discards data packets when I ping to peer after connected the router to MPLS network. but I replaced the router 805 with cisco 1721,everything is going well. why?
configs are as follows:
ip address 172.28.169.1 255.255.255.224
