This routing Protokol is an exterior routing protocol. It’s not neede on local area networks. It’s neede converge the internet. It’s completly different from the internel routing protocols like OSPF, EIGRP, RIP or IS-IS. Here is a basic overview: It’s used to route between AS (autonomous systems) It’s an enhanced vector routing protocol uses tcp for transissions, three way handshake, port 179 support cidr triggered updates granular metrics garanteed to be loopfree Defintion of ...

router ospf 1 redistribute eigrp metric for example redistribute eigrp 1 metric 1 subnets The subnets variable is responsible for redistributing subnetted networks. Without this variable, only networks that are not subnetted are redistributed. Full story

The formula N(N-1)/2 calculates the number of connections needed for a full mesh. 5 routers for example need 10 pvc’s for the full mesh. 5*4/2=10. It’s easier to make a table and write down the connections first before configuering frame-relay. For example here are the serial interfaces with the dlci. S1      S2      ... Full story

11. Refer to the exhibit. Network administrators have set up a hub and spoke topology with redundant connections using EIGRP. However, they are concerned that a network outage between Router R1 and Router R2 will cause traffic from the 10.1.1.x network to the 10.1.2.x network to traverse the remote office links and overwhelm them. What command should be used to configure the spoke routers ... Full story

21. Refer to the exhibit. What three statements are true about the IS-IS configuration? (Choose two.) A. The router is in area 49.0001.0002. B. The router has a system ID of 0003.0004. C. The router acts as a Level 1-2 router. D. The network service access point selector (NSEL) byte has a value of ... Full story

1. Refer to the exhibit. Which statement is true about the 6.6.6.0/24 prefix? A. If another path advertises the 6.6.6.0/24 path and has the default local preference, that path is more preferred. B. The command neighbor send-community is configured on BGP neighbor 10.10.23.3. C. The route 10.10.23.3 is not being advertised to other BGP neighbors. ... Full story
