[KLUG Members] routing question

[Russell Yonkers]

What is Zebra and what does it do??

Also I see the static route to 0.0.0.0 for I think it
is called a gateway of last resort?  Will this work
with RIP2?  Will the Linux box work with RIP2?  

Reason I am asing about RIP2 is that we do not get
into OSPF in the class (only teaching to a CCNA
level).
