Hi,
We have two VSS clusters interconnected via a trunk allowing two VLANs.
Both VSS clusters have an SVI for both VLANs.
Problem is that I cannot ping the IP address of SVI cluster number one from number two and vice & versa.
However I can ping a PC connected to cluster number two from cluster number one in the same VLAN.
If I try to ping the same PC from cluster number two specifying another source, it fails...
I have noticed that the MAC address used for the SVI on both cluster is the same.... I believe this is the problem.
Here is the output:
Cluster one:
Vlan50 is up, line protocol is up
Hardware is Ethernet SVI, address is 0008.e3ff.fd90 (bia 0008.e3ff.fd90)
Description: Infoblox
Internet address is 10.30.0.2/24
Cluster two:
Vlan50 is up, line protocol is up
Hardware is Ethernet SVI, address is 0008.e3ff.fd90 (bia 0008.e3ff.fd90)
Description: Infoblox
Internet address is 10.30.0.3/24
As a result of this, here is a strange STP output: (show spanning-tree vlan 50 from Cluster number two)
VLAN0050

Po3 Desg FWD 20000 128.2563 P2p
Po4 Desg FWD 20000 128.2564 P2p
We can see that the Bridge ID is the same as the Root ID although this bridge IS NOT THE ROOT
Is there a way to change the MAC address of the SVI with IOS-XE, Version 03.05.02.E
