I am trying to test external routed access into the fabric. See attached.

I am running OSPF and the neighbours are formed and I have ACI prefixs on the external switches and the ACI fabric is learning my loopback:

Cisco-3750-01#sho ip route os

Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2

i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

ia - IS-IS inter area, * - candidate default, U - per-user static route

o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP

+ - replicated route, % - next hop override

[110/20] via 100.1.1.1, 01:15:23, GigabitEthernet1/0/47

I am advertising into the fabric loopback100 (3.3.3.3) from the switch:

Leaf-1# show ip route vrf Test_Lab:CTX1

IP Route Table for VRF "Test_Lab:CTX1"

'*' denotes best ucast next-hop

'**' denotes best mcast next-hop

'[x/y]' denotes [preference/metric]

*via 100.1.1.2, eth1/25, [110/11], 00:43:33, ospf-default, intra

I have a ANY contract between L3EPG and WEB EPG and my VM is in Web EPG. The problem I have is that I can not ping from External(loopback) to VM and from VM to External (loopback).

Should there be an entry in the endpoint cache for my loopback address on the switch?

I don’t have any internal vlan for the L3EPG :

Leaf-1# show vlan

Hello

It seems you made the subnets in the in the BD public which is good. Now the other question, did you associate the External L3 to the BD under L3 outs? Also, what does the configuration for External L3 EPG have as its subnets? You mentioned you had an "any" contract but not what subnets are specified.

More pictures would be helpful. Looking forward to your response.

Thanks again for using SupportForums.

Hi

I have associated the External L3 to the BD (see attached) and the subnet is 0.0.0.0/0 which I believe should cover all subnets advertised?

The contract used defined is unspecified ethernet type (see attached).

Thanks for your help.

We all make mistakes right!

Default gateway on the VM was incorrect.

This is now resolved.
