Replicate prefix received at head-end of service chain to appropriate

table depending on address-family.

Family service-chain address-family Replication Table

EVPN INET InetTable EVPN INET6 Inet6Table INET INET EvpnTable

INET6 INET6 EvpnTable

Parameters

partition	- Reference to DBTablePartition where the service-chain route is to be replicated
route	- Reference to service-chain route
table	- Reference to BgpTable where service-chain route is to be replicated
prefix	- Prefix
create	- when "true" indicates that route should be created if not found and

EVPN prefix received at head end of service-chain. Replicate route to <vrf>.inet[6] table depending on whether the EVPN prefix carries inet[6] traffic.

EVPN route carrying inet prefix

Create case. Create route if not found.

EVPN route carrying inet6 prefix

Create case. Create route if not found.

INET/INET6 prefix at head end of service-chain. Replicate route to <vrf>.evpn.0 table.

Create case. Create route if not found.

Check if route belongs to connected table. For EVPN, connected routes could belong to INET or INET6 AF. For routes in the destination table we can use template AF.

Check if EVPN route being re-originated is Type 5 Also make sure that the address-family of the prefix carried in the EVPN route matches the service-chain family. This will avoid the routes from being re-originated twice.

private

Process service-chain path and add to service-chain route if needed.

Parameters

path_id	- PathID
path	- Path to be processed
attr	- Path attribute
route	- Reference to Service-Chain route
partition	- Reference to DBTablePartition where the service-chain route is to be replicated
aggregate	- "true" indicates aggregate route
bgptable	- BgpTable the service-chain route belongs to

If inserting into EVPN table, the label should the vxlan_id of the connected RI if non-zero and if not, the VNI.

Check if there is an existing path that can be reused.

Remove existing path, new path will be added below.

No existing path or un-usable existing path Create new path and insert into service-chain route
