TS1 DHCP on vlan 12 at sw2 acl was there. user was in wrong vlan.
TS2 PPP R17 encap frame-relay need to configure it complete, R12 DHCP default-router ip was wrong.
TS3 OSPF
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 .
TS4 EIGRP a bit different initially no route was coming in R11. R12 has a acl. port on R13 towards R14 was passive.
TS5 BGP. 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 8.8.8.8 not going via exact route its going R1-r5-r22-r21-.6–8.8.8.8 again try my best and found a route-map on R5 setting a diff value as a next-hop mistakenly set to 123.5.5.5. want to set it r21 loopback but mistakenly set it wrong. trace for 8.8.8.8 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 194.1.1.1 goes via R21 .. change local pref. on R22 and it work all other trace was fine
TS6 IPV6 R25 sending wrong next-hop and network was wrong adv. R22 make neighbor on R22
correct it and it work fine for me
TS7 DMVPN 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 .
TS8
MPLS again very different asking for user 105 right hand side remote side to trace to 8.8.8.8 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 .
TS9 nothing diff . crypto was wrong
TS10 NAS 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 .
