CCIE R&S v5 Exam Review on 04 March 2015
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
Configuration is almost same as shared in this forum.
Got rstp, vrf, eigrp authentication in AS45678, OSPFv3 with different area, NTP authentication.
Netflow question changed to add “Shell processing full” in R17.
I took the advice from forum and planned the sequence of configuration in core network, used copy and paste to speed up the process (a method cisco advised to in the lab too)
2.1 -> 2.2 -> 3.1 (use mpls ldp autoconfig area 0)
2.3 -> 2.7 -> 3.3 -> 3.4 -> 2.4
2.5 -> 5.2 -> 3.2 -> 2.6 -> 2.8
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.
