2. Trace route across VLT domains may show extra hops.
3. IP route symmetry must be maintained across the VLT domains. Assume if the route to a destination
is not available at C2, though the packet hits the MY_STATION_TCAM and routing is enabled for that
VLAN, if there is no entry for that prefix in the routing table it will dropped to CPU. By default, all
route miss packets are given to CPU. To avoid this static entry must be configured.
4. There could be L3 frames received out-of-order at the L3 cloud, when a MAC is removed and added
back. This could happen when proxy-routing and sub-optimal routing intersperse each other.
5. This feature is not supported for IPv6.
6. ICL shut – Assume ICL between C1 and D1 is shut and if D1 is secondary VLT then one half of the
inter DC link goes down. After vm motion, If a packet reaches D2 with the destination MAC address
of D1, it may be dropped. This behaviour is applicable only in the LLDP configuration; In static
configuration, the packet will be forwarded.
7. Any L3 packet that was originally should have been switched across domains, when gets a hit at
my_station_tcam (because of this feature) and routed, will have a TTL decrement as expected.
