Very happy to inform you all that I have passed R&S Lab last week, This forum is really awesome so are the people who are always ready to help.
I am sharing details here:
TS Section: I was able to complete this within 2.30 hours with proper checks and fail over tests. Diag Section: I feel that i did all 3 three correct. Config: very straight forward, only 1 or 2 points changed from the material discussed here in forum.
================== Details of TS:
TS1: i- sw2 interface connected to host was in wrong VLAN. ii- int vlan 100 was not advertised in OSPF.
TS2: i- R17 was configured with chap callout. ii- telnet not allowed in line vty. iii- ppp ipcp was missing.
TS3: i- max-lsa was configured either on R3 or on R5 (sorry i forgot the device). ii- I also removed passive interface but from which device i didn’t remember (really sorry for this)
TS4: i- Delay 1000 command on R13. ii- passive interface on R12 towards R14. No ACL, prefix-list or offset-list was there to deny any prefix or change the metric.
TS5: out of 4 traces required, only 2 were taking wrong path, i- For internet prefix 194.x.x.x, I made changes on R21 prefix-list to influence the LP towards R3-R5. ii- For 134.x.x.x prefix MED is changed on R4 to have both routes installed in R12 routing table.
TS6: i- Changed next-hop on R25 to the correct one. ii- IPv6 Network advertisement on Internet router.
TS7: i- nhrp authentication wrong on R18. ii- ip map multicast wrongly configured on R19. iii- WAN interface redistributed on R15.
TS8: i- no default route originated on R7. ii- ip nat outside missing. iii- ospf wrongly redistributed on R8 & R7 as for from Hub to spoke traffic it was making R8 primary. iv- path was wrongly preferred between R4-R6.
TS9: i- crypto pre-share key was wrong on R24. ii- no default route on R7
TS10: i- “ip nat outside source …” command on R23… changed to “ip nat inside source…” ii- transport input telnet was missing on NAS router.
Details of Diag:
Tkt1: Port security issue. Interface was down-down. Tkt2: R15 .. route-map missing on redistribute connected in EIGRP Tkt3: i. Asymmetric routing with Unicast RPF. ii- took some time to arrange the points in right order (please read carefully while doing the same)
Configuration Section:
MST strongest Authentication in EIGRP As 45678 BGP in vrf to build the tunnel, so need to use command “tunnel vrf vrf-name” on tunnel interfaces
