Hello experts,
I have a simple topology below.
Edge1---Core---Edge2
| |
| |
PC1 PC2
Edges HW: C9300-24T
Edges SW: 17.03.04
PC1 and PC2 are in vlan 998. Vlan 998 is stretched between Edges using VXLAN. Edge1 and Edge2 have SVI 998 configured.
From Edge1(SVI998) I can ping PC1 and PC2.
From Edge2(SVI998) I can ping PC1 and PC2.
The question is, Why can't I ping Edge2(SVI998) from Edge1(SVI998) and vice versa. In ARP table I see "Incomplete" records. HSRP and OSPF between SVI998 of Edges don't work either.
I couldn't find if it is expected behavior or not.
If in this topology, Сat9300 is replaced with Nexus9300, then this problem is not observed.
Network topology and Edge's configurations you can find in the attachment.
