Option Description
MTU
Edit the maximum transmission value for the data packets if required.
The MTU value cannot be higher than the MTU value set on the edge
gateway interface. See “Specify Global Configuration,” on page 15 for
information about he MTU set for the default edge gateway.
Description
(Optional) Type a description for the static route.
5 Click OK.
What to do next
Configure a NAT rule for the static route. See “Add an SNAT or DNAT Rule,” on page 68 .
Add a firewall rule to allow traffic to traverse the static route. See the following topics:

“Add an Edge Gateway Firewall Rule,” on page 31

“Add a Trust Groups Firewall Rule,” on page 35
Configure BGP
You can configure Border Gateway Protocol for vCloud Air to exchange routes between your on-premises
border devices and vCloud Air. BGP makes core routing decisions by using a table of IP networks or
prefixes, which designate network reachability among multiple autonomous systems.
The BGP border devices established a connection before any routing information is exchanged. After
establishing the connection, the border devices exchange routes and synchronize their tables. Each border
device sends keepalive messages to keep this relationship alive.
Procedure
1 Log in to vCloud Air and navigate to the vCloud Edge Gateway Services UI.
See “Log In and Navigate to Advanced Networking Services,” on page 9 for information.
2 Click the Routing tab and BGP.
3 In BGP Configuration, complete the BGP options:
a Click Edit next to BGP Configuration.
b Click Enable BGP.
c For packet forwarding to be uninterrupted during restart of BGP services, select Enable Graceful
Restart.
d To allow the edge gateway to advertise itself as a default gateway to its peers, select Enable
Default Originate.
e Type a value (a globally unique number between 1-65534) for the Local AS.
vCloud Air assigns the local autonomous system (AS) number to the edge gateway you are
configuring and advertises the local AS when the edge gateway peers with routers in other
autonomous systems. The path of ASs that a route traverses is used as one metric when selecting
the best path to a destination.
f Click OK.
4 In Neighbors, configure the routing neighbors:
a
Click the Add ( ) icon.
b Type the IP address of your on-premises border device that vCloud Air connect to.
