Restrictions and guidelines: Distributed SRv6 gateway configuration
Make sure a VSI interface uses the same MAC address to provide service on distributed SRv6 gateways connected to IPv4 sites.
If both ARP flood suppression and local proxy ARP are enabled on a distributed SRv6 gateway, only local proxy ARP takes effect. As a best practice, do not use these features together on distributed
SRv6 gateways.
Distributed SRv6 gateway tasks at a glance
To configure a distributed SRv6 gateway:
1.
Creating a VSI
2.
Configuring an EVPN instance
3.
Configuring SRv6 SIDs
4.
Configuring a VSI interface as a distributed SRv6 gateway
5. Configuring packet forwarding methods
Configuring the route recursion mode
Configuring SRv6 TE policy traffic steering
This task is required when the SRv6 TE or SRv6 TE and SRv6 BE hybrid mode is used.
6.
Mapping ACs to a VSI
7. Configuring PEs to exchange BGP EVPN routes
8.
Specifying a source address for the IPv6 packets encapsulated by a distributed SRv6 gateway
9.
Configuring BGP EVPN route redistribution and advertisement
10.
Managing remote MAC address entries and remote ARP learning
Prerequisites for distributed SRv6 gateway configuration
For a VM that requires access to the external network at Layer 3, specify the VM's VSI interface on the border gateway as the next hop by using one of the following methods:
•
Configure a static route.
•
Configure a routing policy, and apply the policy by using the apply default-next-hop or apply next-hop command. For more information about configuring routing policies, see routing policy configuration in Layer 3—IP Routing Configuration Guide .
