Which three statements are correct about EVPN route types? (Choose three.)
- A. Type 5 routes carry replication information.
- B. Type 2 routes carry endpoint MAC address information.
- C. Type 2 routes carry endpoint IP address information.
- D. Type 1 routes carry endpoint MAC address information.
- E. Type 3 routes carry replication information.
Answer: B,C,E
Explanation:
Cisco explains it better: The EVPN control plane advertises the following types of information:
Route type 1 - This is an Ethernet Auto-Discovery (EAD) route type used to advertise Ethernet segment identifier, Ethernet Tag ID, and EVPN instance information. EAD route advertisements may be sent for each EVPN instance or for each Ethernet segment.
Route type 2 - This advertises endpoint reachability information, including MAC and IP addresses of the endpoints or VTEPs.
Route type 3 - This performs multicast router advertisement, announcing the capability and intention to use ingress replication for specific VNIs.
Route type 4 - This is an Ethernet Segment route used to advertise the Ethernet segment identifier, IP address length, and the originating router's IP address.
Route type 5 - This is an IP prefix route used to advertise internal IP subnet and externally learned routes to a VXLAN network.
NEW QUESTION 45
BGP multipath or multihop are not configured in your network.
In this scenario, what is the correct sequence for BGP active route selection?
- A. higher local preference
shortest AS path
lowest router ID
lowest peer address
lower origin code - B. higher local preference
shortest AS path
lower origin code
lowest router ID
lowest peer address - C. higher local preference
lowest router ID
lowest peer address
lower origin code
shortest AS path - D. higher local preference
shortest AS path
lowest peer address
lowest router ID
lower origin code
Answer: B
Explanation:
BGP Path Selection process follows this order
1.Weight (Bigger is better)
2. Local preference (Bigger is better)
3. Self originated (Locally injected is better than iBGP/eBGP learned)
4. AS-Path (Smaller is better)
5. Origin
6. MED (Smaller is better)
7. External (Prefer eBGP over iBGP)
8. IGP cost (Smaller is better)
9. EBGP Peering (Older is better)
10. Router- ID
