In this way, the confederation preserves next hop, metric, and local preference information. To the outside world, the confederation appears to be a single AS. With this solution, iBGP transit AS problems can be resolved as iBGP requires a full mesh between all BGP routers: large number of TCP sessions and unnecessary duplication of routing ...

The Next Hop Resolution Protocol (NHRP) is an extension of the ATM ARP routing mechanism [1] that is sometimes used to improve the efficiency of routing computer network traffic over a non-broadcast, multiple access (NBMA) network. [2] It is defined in IETF RFC 2332, [3] and further described in RFC 2333. [4]
A routing table usually consists of a list of possible destination networks or IP addresses for which the next hop is known. By only storing next-hop information, next-hop routing or next-hop forwarding reduces the size of routing tables. A given gateway only knows one step along the path, not the complete path to a destination. If no next hop ...
Administrative distance (AD) or route preference [1] is a number of arbitrary unit assigned to dynamic routes, static routes and directly-connected routes. The value is used in routers to rank routes from most preferred (low AD value) to least preferred (high AD value).
HP OpenView is the former name for a Hewlett-Packard product family that consisted of network and systems management products. In 2007, HP OpenView was rebranded as HP BTO (Business Technology Optimization) Software when it became part of the HP Software Division.
It then forwards the packet along to the next router in the path, which swaps the packet's outer label for another label, and forwards it to the next router. The last router in the path removes the label from the packet and forwards the packet based on the header of its next layer, for example IPv4. Due to the forwarding of packets through an ...
Multi-path routing can be used in conjunction with most routing protocols because it is a per-hop local decision made independently at each router. It can substantially increase bandwidth by load-balancing traffic over multiple paths; however, there may be significant problems in deploying it in practice.
