問題文
A core switch at a large site should learn the remote Auto VPN subnets from the appliance so that nobody has to maintain static routes on the switch any more. The appliance runs in Routed mode and the site is built on five VLANs that cannot be collapsed. Which statement should guide the decision?
選択肢
- OSPF advertisement requires BGP on the appliance first, so the site has to move from Auto VPN to a BGP peering with the core switch.
- OSPF advertisement in Routed mode needs the Single LAN setting, so keeping the five VLANs means keeping the static routes on the switch.
- OSPF advertisement in Routed mode needs MX 13.4 firmware on the appliance, so an upgrade removes the static routes to the VPN subnets.
- OSPF advertisement carries only the local VLAN subnets, so the switch still needs a static route for everything that sits behind the VPN.
