RE: OSPF & NAT

2001-02-20 Thread Curtis Roze 

ios supports it or redistribute the 10.10.10.100/32 into ospf via a static
ip route 10.10.10.100 255.255.255.255 null0 statement.

Hope this helps.

Subject: OSPF & NAT

Hi Guys can you help me
 

I've set up a static NAT entry on a remote dual ethernet router(name
of router is remote1), the global address that the local device will
translate to is 10.10.10.100 this Global address is not in the subnet of
the IP address on either interface, so I have set up a loopback address
with IP address 10.10.10.1/24 and have placed it in the OSPF process on
the remote router( network 10.10.10.0 0.0.0.255 area 1), so that other
routers in the same OSPF group will see the advertised Global network, (
as all Global addresses will be in the 10.10.10.x/24 network), and know
where to send any data that has been translated.
However on a Core router that is attached to remote1 via it's
ethernet0, and is on the same OSPF process as remote1, when "show ip
route" is typed on the Core router this is observed.
O 10.10.10.1/32 [110/11] via 10.1.1.33, 00:16:08, Ethernet0.
Instead of the whole 10.10.10.0/24 network being advertised, only the
explicit address of remote1 has been advertised.
therefore the global NAT address of 10.10.10.100 is unknown to other
routers besides remote1.
What do I need to do to get the whole 10.10.10.0/24 network being
advertised via OSPF, so that the other routers will know where to send
NAT data.
Is the only way is to set a static route at the core router and
redistribute it.
 
Thanks in advance
