In WB2 lab10 Task3.1 it tells that R2 R4 and R5 are not allowed to use frame-map statements neither should sub-interfaces be used on any FR routers. This lead to using PPPoFR as no frame-maps will be needed. Later int Task 4.1 it says to use R2 as DR and R4 as BDR. This should not be a problem but the issue is that it tells us NOT to use "ip ospf network" command. Is this not contridicting.
Anyway the DSG uses physical interfaces for the FR cloud. with R2 as DR and R4 as BDR keeping the frame maps and using the default OSPF NBMA type. I tried using PPPoFR (no frame maps) and changing the OSPF network to BROADCAST in order to have a DR and A BDR but this solution treats each Virtual-Access interface as a seperate P2P broadcast link, Thus we end up with a DR and a BDR on each link. see output below for R2 and R6 as an example: R2 --- interface Serial0/1/0 no ip address encapsulation frame-relay no dce-terminal-timing-enable frame-relay interface-dlci 214 ppp Virtual-Template1 frame-relay interface-dlci 215 ppp Virtual-Template1 frame-relay interface-dlci 216 ppp Virtual-Template1 end R2(config-router)#do sh ip o n Neighbor ID Pri State Dead Time Address Interface 200.0.0.6 1 FULL/BDR 00:00:34 192.168.10.6 Virtual-Access3 200.0.0.5 1 FULL/BDR 00:00:37 192.168.10.5 Virtual-Access2 200.0.0.4 200 FULL/BDR 00:00:36 192.168.10.4 Virtual-Access1 Similarily on R6 we have R2, R4 and R5 as DRs on each Virtual-Access interface. Can someone provide any feedback as the DSG does not match the Tasks requiremaents ! -- Best Regards, Saleh Hassan Batouq [email protected] Tel: +968 99365607 Fax: +968 2469690 P.O.Box:1083- Postal Code:112 Muscat-Sultanate Of Oman _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
