While I am going for my Second CCIE R&S Lab attempt soon, I thought before leaving I must post my MPLS TS Strategy in general despite of fact I will get in my TS lab or not :
Ofcourse people who wanna know what went wrong with First attempt, here is the summary : http://ieoc.com/forums/t/15436.aspx
Below are the summary steps:
Step 1
=======
CEF is running on MPLS enabled routers
sh ip cef
Step 2
======
loopback advertised into IGP on CE, Also Check IGP configuration like "no auto summary" and "redistribution seed metric, "autonomous system number in EIGRP VRF Configuration".
sh ip int b | e una
sh run | s r [eor]
Step 3
======
Check if VRF is created and applied to proper interface
sh run | s vrf
sh ip vrf detail
sh run int
Check if CE routes are coming to PE
sh ip route vrf
Step 4
======
Check for VRF route target import and export
sh run | s vrf
Step 5
======
Check if LDP is running all over, mpls ip is configured on MPLS facing interfaces.
sh mpls interface
sh mpls ldp neighbor
Step 6
======
Check for MP-BGP and IGP redistribution,
sh run | s r b
sh run | s r [reo]
Check for redistribute metric, For OSPF look for "match internal external 1 external 2" , For eigrp "redistribution metric" should be mentioned.
Step 7
======
Check for MPBGP Config on all routers, look for things like RR config, neighbor activate, send community extended or both, no synchronization, no auto summary, remote as, update source loopback 0
sh run | s r b
sh ip bgp vpnv4 all summ
sh ip bgp vpnv4 all
Step 8
======
Check for Control plane issues on all routers like:
1. ACL
sh access-list
2. CoPP
sh policy-map control-plane
3. Distribute List, Offset-List
sh run | i distribute offset
4. Route-map
sh route-map
5. Rate Limit
sh run | i rate
6. Next Hop and Route Recursion Issues
7. IGP Timers and Password mistmatch issues
8. PBR
sh run | i policy
