CCIE R&S v5 Exam Review on 4 November 2015
yes i found it a bit hard one .
DHCP on vlan 12 at sw2 acl was there. user was in wrong vlan.
R17 encap frame-relay need to configure it complete, R12 DHCP default-router ip was wrong.
R5 and R22 have same Router-id change it on R22 to its loopback. R21 and R22 passive interface. remove the passive interface and it works .
EIGRP a bit different
initially no route was coming in R11.
R12 has a acl.
port on R13 towards R14 was passive.
trace was droping on R1 or R2 didn;t remember . i got it my MPLS domain is broken somewhere
check it on R2 and R1 enable mpls everywhere and make ospf neighborship
still trace for 184.108.40.206 not going via exact route its going R1-r5-r22-r21-.6–220.127.116.11 again try my best
and found a route-map on R5 setting a diff value as a next-hop
mistakenly set to 18.104.22.168. want to set it r21 loopback but mistakenly set it wrong. trace for 22.214.171.124 still going via above path …left it as it take my 12 to 15 minute and it still not working fine ..
i know this thing it will create i problem in my MPLS. ( i soved it in the end )
then trace to 126.96.36.199 goes via R21 .. change local pref. on R22 and it work
all other trace was fine
R25 sending wrong next-hop
and network was wrong adv.
make neighbor on R22
correct it and it work fine for me
again got stuck in this ticket
As R15 there is no neighborshiop between R15 and R18
check R18 and didn’t find any misconfig
check crypto didn’t find any misconfig
bounce the tunnel still didn’t work
copy paste the crypto and tunnel config of r17
but still didn’t work
very frustating as time was keep going i have give more than12 minutes and not solved and i know bgp is still not solved
check my R14 and found acl was there droping traffic
permit ip traffic and it work for me .
MPLS again very different
asking for user 105 right hand side remote side to trace to 188.8.131.52 and it goes perfectly as it was in my paper ( fault was with mpls which i solved it in my bgp )
second trace was PC 104 left side remote site to right side user PC 105.
pc 104 didnt have any ip address .
it was taking via dhcp .
check sw3 and R9
sw3 was not adv vlan 100 adv vlan 100 in ospf .
dhcp snooping was there on Sw3 ..just remove it …
got the ip and trace it work perfect .
nothing diff .
crypto was wrong
same old problem didn’t remember .
i solve all this in 1:50 min. i know 10 minutes are still there back to my BGP again check everything
finally found i ser wrong next-hop in route-map
change ot to R21 loopback
and it work fine .
i did it in 1:58 minute :-p
R15 exclude nbma
URPF BGP POLICY
ALL same as workbook
finally i did it.
just keep calm keep cool.
number will be yours.
