How many times must BGP be configured when running symmetric IRB with two VFRs?
Answer(s): C
When running symmetric Integrated Routing and Bridging (IRB) with two Virtual Forwarding Routers (VFRs), BGP must be configured twice. Each VFR will have its own BGP instance to handle the routing information.

DRAG DROP (Drag and Drop is not supported)What is the correct order of steps for data flow in asymmetric IRB frame encapsulation?
Answer(s): A
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.

What does the show vian command display?
The show vlan command displays all configured VLANs on the device, including their status, ports, and other relevant details. It does not limit the display to only active VLANs or all possible VLANs but shows those that are currently configured.

Which two things does the no vrrp 100 address-family ipv6 command delete?
Answer(s): A,D
The no vrrp 100 address-family ipv6 command deletes the VRRP (Virtual Router Redundancy Protocol) identifier (A) and the address-family configuration (D) for VRRP group 100. This effectively removes the VRRP configuration for the specified address family.

An administrator obtains the following CLI output:How much time does the local system take to detect remote failures without receiving packets?
Answer(s): B
The local timers in the BFD (Bidirectional Forwarding Detection) configuration show a detect multiplier of 4 and a receive interval of 300ms. The time taken to detect remote failures is calculated
