What is the default OSPF network for the following media types: Ethernet, Token Ring, and FDDI? Highlight for answer: Broadcast 2. What OSPF router type connects one or more areas to the backbone and acts as a gateway for interarea traffic? Highlight for Answer: Area Border Router (ABR) 3. To be in compliance with the BGP synchronization rule, there must be a match for the prefix in the IP routing table in order for an internal BGP (iBGP) path to be considered a valid path. What additional criteria must an OSPF route meet?Highlight for answer: The OSPF router ID must match the BGP router ID of the iBGP neighbor. 4. Give at least two possible reasons as to why the prefix 150.1.2.0/24 is experiencing a RIB-failure: R1> sh ip bgp BGP table version is 5, local router ID is 200.200.200.1 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure Origin codes: i - IGP, e - EGP, ? - incomplete Network          Next Hop            Metric LocPrf Weight Path r> 150.1.2.0/24       10.1.1.2                   0    110      0 300 i *> 155.1.123.0/24   10.1.1.2                   0    160      0 300 i Highlight for answer: Generally this is due to the existence of a route with a lower AD in the IP routing table.  This can also be due to a memory error or the number of routes in VRF exceeding the route-limit configured under the VRF instance (outside of the scope of the Routing and Switching lab…) 5. What is the difference between OSPF neighbor and adjacencies? Highlight for answer: A neighbor is another OSPF router that is attached to one of the first router's directly connected links. An OSPF adjacency is a conceptual link to a neighbor over which LSAs can be sent. --------------------------------------------------- Images: --------------------------------------------------- --------------------------------------------------- Post date: 2009-04-28 13:40:29 Post date GMT: 2009-04-28 05:40:29 Post modified date: 2009-04-28 13:41:31 Post modified date GMT: 2009-04-28 05:41:31 ____________________________________________________________________________________________ Export of Post and Page as text file has been powered by [ Universal Post Manager ] plugin from www.gconverters.com
