OSPFv3 as a PE-CE routing protocol Many Service Providers (SPs) offer the Virtual Private Network (VPN)nservices to their customers, using a technique in which Customer Edgen(CE) routers are routing peers of Provider Edge (PE) routers. ThenBorder Gateway Protocol (BGP) is... M Lundberg,...
Intermediate System-to-Intermediate System (IS-IS) is a dynamic routing protocol designed by the ISO to operate on the connectionless network protocol (CLNP). IS-IS was modified and extended in RFC 1195 by the IETF for application in both TCP/IP and OSI reference models, called "Integrated ...
The term “router” in this document refers to a router in a generic sense or an Ethernet switch running routing protocols. 1.1 IS-IS Overview Intermediate System-to-Intermediate System (IS-IS) is a dynamic routing protocol designed by the International Organization for Standardization (ISO) to ...
As adynamic routingprotocol, OSPF not only routes IP packets based on the destination IP address (given in the packet header), but it also detects topological changes in the AS. After detecting changes, OSPF calculates new, loop-free routes after a short period (known as convergence time) in...
If multiple routes to the same destination are discovered by different routing protocols running on the same device, the route discovered by the protocol with the highest priority is selected. For example, if both OSPF and IS-IS are configured on a network, the route discovered by OSPF is use...
Protocol Type Carried by IP Format:protocol-number|icmp|tcp|udp|gre|igmp|ip|ipinip|ospf An advanced ACL can filter packets based on protocol types, such as ICMP (protocol number 1), TCP (protocol number 6), UDP (protocol number 17), GRE (protocol number 47), IGMP (protocol number 2),...
Routing Information Protocol (RIP) is a distance vector protocol that uses hop count as its primary metric. RIP defines how routers should share information when moving traffic among an interconnected group of local area networks. In the enterprise, Open Shortest Path First (OSPF) routing has larg...
The Import mode enables BGP to import routes by protocol type, such asRIP,OSPF,IS-IS, static routes, and direct routes. The Network mode imports a route with the specified prefix and mask to the BGP routing table. This mode is more precise than the Import mode. ...
protocol. A router that uses a dynamic routing protocol automatically generates routing information, shares that information with other routers, and updates the information when routing changes occur. A large internetwork that primarily uses dynamic routing typically also uses some manually configured ...
