I have a WAN with Cisco 1841 routers.
RouterA FE0/0 10.20.10.42/30
RouterB FE0/0 10.20.10.34/30
I have a DHCP server hanging off RouterA FE0/1 with ip 192.168.1.153
From RouterA I can ping my DHCP server.
When I connect to RouterB I can ping the FE0/1 interface on routerA but I cannot ping the DHCP server. Yet when I do a traceroute from RouterB the trace hits the FE0/0 interface on router and times out.
I have put in a static mac-address for my DHCP server on RouterA but somehow the mac address does not stay in the address table. After I have added the mac-address and do a sh mac- the table is empty. When I issue the sh arp command I see the 192.168.1.153 hhhh.hhhh.hhhh entry
Does anyone know what I can try to ping my dhcp server from RouterB? If it means I need to add the static mac in like I amtrying to do what do I need to do to make the mac entry stay in the mac table?
I am running IOS flash:c1841-advipservicesk9-mz.124-25a.bin onboth routers.
