So it seems pretty obvious that the source address of 10.16.0.0/24 is not being allowed across the 19.168.201.253/192.168.40.253 path.
Just to compare in our production network and our production router whihc Im trying to replace I get the following from my laptop when trying to get to 10.3.11.1:
C:\Documents and Settings\kam.khan>tracert 10.3.11.1
Tracing route to 10.3.11.1 over a maximum of 30 hops
1 76 ms 1 ms 1 ms 10.16.10.236
2 8 ms 7 ms 7 ms 10.0.3.193
3 8 ms 8 ms 8 ms 10.3.11.1
Trace complete.
C:\Documents and Settings\kam.khan>
So all traffic hits this router and im assuming the 10.16.10.236 has access lists on it with PBR allowing it to route all 10.16.0.0./16 traffic for 10.3.11.0/24 down its MPLS (of whihc 10.3.193 is its first hop). I want 10.16.10.145 to do this! But the problem is 10.16.0.0/16 goes another route!
Arhh!
what do you think?!
may be I need to get the ISP for the MPLS to do some source filtering...
Much thanks agian
