CCIE R&S v5 Exam Review on 04 March 2015

CCIE Real Lab Workbook

CCIE R&S v5 Exam Review on 04 March 2015 No ratings yet.

Got the 5 digits number this morning.

My lab exam was almost the same as lab 1.2. Here are what I experienced.

Spent 1.30 hours in troubleshooting.
1: Port security on SW3 e1/0, change mac address to PC e0/0 mac address
2: R17 has ‘ppp authentication chap callout’ on s4/0, remove it and TELNET from R11 to check connectivity
3: R21 with ‘ip ospf cost 1’ on the interface face to R22, remove it to match the desire metric and cost shown in the output from question
4: R13 had ‘delay 1000’ in one interface, remove it, and also configure metric weight 0 1 1 1 1 1 on all the routers to match the desire metric and cost shown in the output from question
5: On R12 add “maximum path 2” to match the desire metric and cost shown in the output from question
6: R22 route-map has a wrong next hop ipv6 address, change to the ipv6 address of R22
7: ip nhrp mapping was wrong on both multicast and NBMA R18 and R19. Refer to R17 int t0 for the correct configuration. R15 missing ‘no ip split-horizon eigrp’.
8: Spent some time on this ticket. R3/R4 route-target import and export was not complete, add import RT from R5/R6. R7/R8 redistribute static default route into BGP, R3/R4 able to receive, therefore even ‘default-originate’ was missing in R7/R8, I ignored it. R3/R4 missing network advertisement of link between R3/R4 and R7/R8 in vrf, add them. Ping and traceroute from remote site to Hub and Internet was successful. After I shutdown R7 to check failover to R8, found R8 e0/0.125 missing ‘ip nat outside’. Also increase the ip ospf cost on the link between R4/R6 to make failover work. Used ‘clear ip bgp * ‘ during failover test to speed up the process.
9: Mismatch in isakmp policy of R24 and R7, fix it and ping went through.
10: NAS e0/0 has a configured mac-address, due to this it has another DHCP ip address (192.168.1.3) instead of 192.168.1.200 which is used in R23 NAT. Change the configured mac-address to the one defined in the ip dhcp pool of R23 to get ip address 192.168.1.200.

Diag is same as workbook 


2.9 -> 2.10 -> 2.11

With this planned sequence I was able to finish the lab around 2pm and start to do checking or verification again.
