Testing Procedure

  1. Ssh to one of the Shared Services hosts (either NLB :8033 or :8044)

    1. Ping the other SharedServices host

  2. Realize the pings don’t work b/c MSR routes are not in place on the Shared Services Web Tier RTs

    1. 10.100.4.0/22 Local CIDR needs a new Next Hop in RT for Sub01 & Sub02

      1. Sub01 route should oppose the 10.100.5.0/24 VPCE
      2. Sub02 route should oppose the Sub01 VPCE

      ssrt ss-route

  3. Search for the internal IP of the EC2 Hosts in shared services Spoke
