my first MPLS

Hi friends i have on my table mikrotik RBs configuration like in example
http://wiki.mikrotik.com/wiki/MPLS_Lab_Setup (MPLS,OSPF like in example)
I connect router PE2 to internet and i connect my PC to PE1.see it in the attach picture.

On the PE2 i have static default route to 10.10.10.1
AND PE2,P1,P2,P3,PE1 has distribute-default=as-type-1

I can ping PE2 (10.10.10.2 )from my PC(192.168.1.2) but nothing beyond PE2(10.10.10.1). WHY?

Thanx.

Hi,

Send us traceroute from pc to internet. Lets see how far it goes.

C:\Users\ja>tracert 8.8.8.8

Tracing route to 8.8.8.8 over a maximum of 30 hops

1 <1 ms <1 ms <1 ms 192.168.1.1
2 <1 ms <1 ms <1 ms 10.1.0.254
3 <1 ms <1 ms <1 ms 10.0.255.6
4 <1 ms <1 ms <1 ms 10.2.0.1
5 * * * Request timed out.
6 * * * Request timed out.
7 * ^C
C:\Users\ja>

From PE2 i can ping 8.8.8.8

Does your internet router (10.10.10.1) have a static route to 192.168.1.0 pointing to 10.10.10.2?
If not, then that’s the reason. Either your Inernet router needs to know all of the IP addresses in your lab, or else the lab’s Internet gateway needs to do masquerading as it hands packets up to the Internet. Just masquerading is the simplest solution.

Yes.So simple.
i set masq for out interface Ether2 on PE2.


Thanks

Give that man his God damn blood earned karma points!!! :laughing:

I have in one path 5 routers (workstations-rb1rb2rb3rb4rb5-GATEWAY)
R1-R2 are static routed
I want reconfigure my static routed network to MPLS for better performance,is it good idea?

Have i reconfigure or not?

It really doesn’t matter for performance reasons. The only reason you might want to use routing instead of simple NAT is if you have other devices “upstream” from the MPLS network, and you want those devices to be able to directly reach those devices inside of or “downstream” from the MPLS network.

Try both and see what works differently in each situation. That’s the point of a lab, right?

Hahahaha - well, you can always upvote my post too yaknow. :wink:
