What is the correct order of steps for data flow in asymmetric IRB frame encapsulation?
Correct Answer:
Explanation:
* Ingress VTEP performs a route lookup that is based on the destination IP address.
* Ingress VTEP encapsulates the packet with VXLAN and sends it on the appropriate VNI segment.
* Egress VTEP determines that the host is local to the VNI and switches the packet.
* Egress VTEP bridges the packet after decapsulation.
Steps and Correct Order:
* Ingress VTEP performs a route lookup that is based on the destination IP address.
* The ingress VTEP (Virtual Tunnel Endpoint) first needs to determine the next hop for the packet.
This involves performing a route lookup using the destination IP address.
* Ingress VTEP encapsulates the packet with VXLAN and sends it on the appropriate VNI segment.
* Once the route lookup is complete, the ingress VTEP encapsulates the packet in a VXLAN header, which includes the appropriate VNI (VXLAN Network Identifier) segment, and forwards it.
* Egress VTEP determines that the host is local to the VNI and switches the packet.
* The egress VTEP receives the encapsulated VXLAN packet, decapsulates it, and then checks its local VNI to determine if the destination host is within the same VNI.
* Egress VTEP bridges the packet after decapsulation.
* After determining the destination host's locality, the egress VTEP bridges the packet to the appropriate interface to deliver it to the final destination.

A customer must configure a peer link between two switches in the L2 MC-LAG scenario.
SwitchB has already been configured. Configure the peer link on SwitchA.
Use the following configuration information:
MC-LAG domain 1
VLAN 101
Peer link Port-Channel 100
SwitchA IP: 192.168.1.1/24
SwitchB IP: 192.168.1.2/24
MC-LAG system MAC: 00:00:00:11:11:11
The physical ports to connect the peer switch are Eth 1/5 and Eth 1/6 for each switch.
