Sebastian, As mentioned above CoPP would be a good choice to limit ARP traffic to the router. You need to trace down that MAC Address and figure out whether its a rogue or perhaps node with micsonfiguration. CoPP or rate limiting will hide the symptoms but will not cure whatever host is causing your issues.

Anyone taken the R and S recently do they offer Secure CRT or Putty? Someone said SecureCRT but they don't offer TAB. Can anyone who actually took the test recently provide feedback?

Peter, Actually you answered my question. I was wondering why RR functionality was needed after you disable client to client reflection but you pointed out that there is also client to nonclient reflection which I hadn't considered in my question. Thanks again.

Thanks Peter actually this is precisely the document I was reading before I asked the question. I see the is still available after you disable reflection.

What is the point of having the command <no bgp client-to-client reflection> and route reflection at all when ibgp clients in a cluster are fully meshed? If the RR is supposed to minimize the need for full mesh and the clients are fully meshed anyway why would route reflection be there in a fully meshed client setup? It is mentioned that the no client to client reflection is necessary if you want IBGP peering etc. so why not just turn off the rr functionality if the clients are already fully meshed?

EIRGP router id is mandatory with IPV6 EIGRP. Is <IPV6 Router EIGRP X >mandatory if you have at least one IPV4 interface configured that can serve as a router EIGRP router id? Could you then get away enabling EIGRPV6 without using the ipv6 router command?

Thanks for the answers. """ EIGRP Scenario: R1==R2==R3==R4 R1 advertises networks 1.1.1.1 and 2.2.2.2. R2 has distribute list out allowing only 1.1.1.1. R1-R2 link goes down. What queries do R3 and R4 receive? """" OK so R2 sends out a query for 2.2.2.2 to R3 and R3 replies it doesn't know and doesn't pass query to R4. How about for 1.1.1.1? Since R3 had 1.1.1.1 in its topology table does it push the 1.1.1.1 query to R4?
