Hello All
Imagine the situation that you know that a problem occurred into your
redistribution in the middle of the lab (time goes by
incredible fast) and one off your goals is to archive that native
prefixes should be reachable through native protocol.
Lets that the router that is performing the route redistribution, we
erase the redistribution configuration. (Please sorry my english)
The show ip route ROUTESOURCE should be sufficient to know which routes
are Native from others, or there is another
better option ? Also I saw recently an email from Petr (hey bro you look
in good shape for the Lab) this:
draw detailed redistribution diagram, place routing protocols as graph
vertexes, with edges (routers that do redistribution)
connecting them.
e.g.
__________(R1)_________
/ \
/ ____(R2)_____ \
/ / \ \
OSPF--(R1)--EIGRP----(R3)----RIP
\ /
\___(R3)__/
Now a quick idea: If you need a loopless routing, you should build SPT here.
Choose a core protocol, and build a spanning-tree, rooted in that protocol.
if you choose OSPF you may end up with
_________(R1)__________
/ \
/ \
/ \
OSPF--(R1)--EIGRP RIP
Could anyone please clarify for me this a little bit better?? lets say
that I have something like Lab 2 from
InternetworkExperts
that is
Protocols................EIGRP(2 to 4).......
Protocols....OSPF.(1 to 4)...................
Routers............1.....2......3........4...
Protocols.........RIP...
Routers...........Sw1...
Lets say that you have to perform route redistribution in all routers
and also that native prefixes should be reachable through native protocol.
