Hi guys, I passed CCIE R&S , below is my feedback:
1: DHCP–>SW1 or SW2 vlan12 was configured with access-list.resolved.
2: PPP–>Encap FR on R12,change to PPP and applied rest config.resolved.
3: OSPF–> pass interface applied on R22 or R21, wrong ospf cost on interface.resolved.
4: EIGRP–>R12 or R13 was configured with pass interface.resolved.
5: BGP –>LDP was broken on R1 and R2, enabled MPLS ip on R2; next hop was configured on R5 with wrong next hop, kept the route map applied; applied with the right next-hop address. resolved.
6: IPV6–> Configured the IPV6 using IPV4 addressing and set the next-hop using route map which were pre configured. resolved.
7: DMVPN –>ACL was applied on R18 Se4/0 interface, ammended the ACL. Apply ip nhrp redirect on R15 and shortcut on R17, 18 and 19. remove ip domain timeout 1 on PC107.resolved.
8: MPLS –> normal faults on R7,R8 established bgp neighborhood B/W R3-R7 and R4-R8. add not-advertise under ospf inter-area summarization. Client was not taking the IP address, checked the client identifier on R9 and fixed the same. Also advertised the VLAN 100 and 200 Subnet in OSPF on SW3.resolved.
9: IPSEC: there’s an ACL on R21 S4/0, permit udp non500-isakmp. resolved.
10: NAS: NAS server with wrong ip address, changed dhcp pool on R23. Resolved
Diagnostic:
1. port security. 2. DMVPN, exclude NBMA address from eigrp. 3. BGP policy, asymmetric urpf. Cofiguration: VRF version.
