-test_bgp_evpn_overlay_index_gateway.py: Test EVPN gateway IP overlay index functionality
-Following functionality is covered:
-
- +--------+ BGP +--------+ BGP +--------+ +--------+
- SN1 | | IPv4/v6 | | EVPN | | | |
- ======+ Host1 +---------+ PE1 +------+ PE2 +------+ Host2 +
- | | | | | | | |
- +--------+ +--------+ +--------+ +--------+
-
- Host1 is connected to PE1 and host2 is connected to PE2
- Host1 and PE1 have IPv4/v6 BGP sessions.
- PE1 and PE2 gave EVPN session.
- Host1 advertises IPv4/v6 prefixes to PE1.
- PE1 advertises these prefixes to PE2 as EVPN type-5 routes.
- Gateway IP for these EVPN type-5 routes is host1 IP.
- Host1 MAC/IP is advertised by PE1 as EVPN type-2 route
-
-Following testcases are covered:
-TC_1:
-Check BGP and zebra states for above topology at PE1 and PE2.
-
-TC_2:
-Stop advertising prefixes from host1. It should withdraw type-5 routes. Check states at PE1 and PE2
-Advertise the prefixes again. Check states.
-
-TC_3:
-Shut down VxLAN interface at PE1. This should withdraw type-2 routes. Check states at PE1 and PE2.
-Enable VxLAN interface again. Check states.

+test_bgp_evpn_overlay_index_gateway.py: Test EVPN gateway IP overlay index functionality
+Following functionality is covered:
+
+ +--------+ BGP +--------+ BGP +--------+ +--------+
+ SN1 | | IPv4/v6 | | EVPN | | | |
+ ======+ Host1 +---------+ PE1 +------+ PE2 +------+ Host2 +
+ | | | | | | | |
+ +--------+ +--------+ +--------+ +--------+
+
+ Host1 is connected to PE1 and host2 is connected to PE2
+ Host1 and PE1 have IPv4/v6 BGP sessions.
+ PE1 and PE2 gave EVPN session.
+ Host1 advertises IPv4/v6 prefixes to PE1.
+ PE1 advertises these prefixes to PE2 as EVPN type-5 routes.
+ Gateway IP for these EVPN type-5 routes is host1 IP.
+ Host1 MAC/IP is advertised by PE1 as EVPN type-2 route
+
+Following testcases are covered:
+TC_1:
+Check BGP and zebra states for above topology at PE1 and PE2.
+
+TC_2:
+Stop advertising prefixes from host1. It should withdraw type-5 routes. Check states at PE1 and PE2
+Advertise the prefixes again. Check states.
+
+TC_3:
+Shut down VxLAN interface at PE1. This should withdraw type-2 routes. Check states at PE1 and PE2.
+Enable VxLAN interface again. Check states.
