TC02: DUT1 and DUT2 route IPv4 bidirectionally over LISP GPE tunnel using physical interfaces and VRF is enabled
[Documentation]
[Top] TG-DUT1-DUT2-TG.
[Enc] Eth-IPv6-LISPGPE-IPv4-ICMPv4 on DUT1-DUT2, Eth-IPv4-ICMPv4 on TG-DUTn.
[Cfg] Configure IPv4 LISP static adjacencies on DUT1 and DUT2.
[Ver] Case: ip6-lispgpe-ip4 - vrf, phy2lisp
Make TG send ICMPv6 Echo Req between its interfaces across both DUTs and LISP GPE tunnel between them; verify IPv4 headers on received packets are correct.
[Ref] RFC6830.

[Documentation]
[Top] TG-DUT1-DUT2-TG.
[Enc] Eth-IPv6-LISPGPE-IPv4-ICMPv4 on DUT1-DUT2, Eth-IPv4-ICMPv4 on TG-DUTn.
[Cfg] Configure IPv4 LISP static adjacencies on DUT1 and DUT2.
[Ver] Case: ip6-lispgpe-ip4 - main fib, virt2lisp
Make TG send ICMPv4 Echo Req between its interfaces across both DUTs and LISP GPE tunnel between them; verify IPv4 headers on received packets are correct.
