Can someone clarify please? Task 13-9 of LAB 13 Vol 1, DSG page 325, says the loopbacks locally configured and advertised in BGP AS 10101 should appear in other ASs as if they had passed through AS 11111 , 11222 , 11333 and 11444. Actually that requirement is implemented on page 327, DSG. that looks OK. However, Task 13-10 (DSG page 327) requires that Cat3 and ALL otehr routers, see one single route represemnring these loopback networks. That is actually done on page 329 of DSG. Of course this confuses me because if we use aggregate-address with summary-only option, the more specific routes will not show up in the others ASs or even other devices within AS 10101. How one is supposed to square these two questions off?
Thanks and regards BAuke
