Re: CCIE SP Mini-Scenarios (New Site)

Thanks for the link and explanations.

What is "better" to do, use "capability vrf-lite" or manually change the tag
or manually change the domain-tag on the ospf process.
Is there any other solution?

This is for " It's also very important to know what to do when the feature
is not available ;)" :)

Regards,

Ciprian
