Duplex Mismatch

I’ve had this happen several times, I connect a 3725 to a 3640 using slot 0 (f0/0) and bam, duplex mismatch… no matter how many times I configure “duplex full” on each interface, one of them goes back to half-duplex. 

 

BGP choosing longer AS_Path as preferred route...

The following network might look familiar if you’re going through the 642-902 book; and, if you are following the reading by configuring the examples in GNS3, you will find an omission which isn’t discussed until several sections later (that discussion does not clarify the problem as there is no mention of a problem with the example… but there is problem!)

no parser cache ...

I was configuring bgp earlier today and incorrectly entered an ip address in the neighbor statement… something like:

Redistribution with a Route Map

(or, how I forgot to remember to change the loopback network type and will remember to never forget in the future...)

The goal is to redistribute OSPF into EIGRP while preventing routes L1, L2, L4,& L6 in OSPF 50 Area 3 from being redistributed (these routes are configured as loopbacks on R3); All EIGRP routes are to be redistributed into OSPF.
