If your not routing on the 6500's where are you going to route? I would personally highly suggest each 4000 link back to the each 6500 and a combination of HSRP and Per VLAN STP be used to balance the use of the gigabit links. As to which 6500 internet traffic uses, I suggest that it really

I don't think that anyone at Juniper or ISP's for that matter would consider the CCIE cert as junior, or in any way lacking in technical difficulty. The issue is one of applicability. ISP's deal at some depth with IP routing which is about 1/2 at most of the CCIE program. As such, the cert

couple comments inserted Howard It's misleading to think that all ISP routers need to be "core." Arguably, the highest-bandwidth "core" routers inside an ISP may not need to run full BGP, but have more stringent demands on OSPF, ISIS, and/or MPLS. Think of RFC 2547 "P" routers. dre IBGP

Re: EBGP multihop question

I'm not sure if I follow you here. I believe the question has to do with how the peering became established in the first place. Simply adding a neighbor statement to a router in no way enables the router to find a route to that particular neighbor. Actually, the issue of routing to remote

Maximum Transfer Units (MTU) have an significant impact on the efficiency of traffic flow. MTU's are set on a per link basis and describe the maximum datagram size permitted on a link. Should a datagram size exceed the particular MTU on a link, the datagram is either dropped or fragmented
