Detailed Description

Configure TCP source addresses, for active-open TCP sessions.

TCP src/dst ports are 16 bits, with the low-order 1024 ports reserved. So, it's necessary to provide a considerable number of source IP addresses if one wishes to initiate a large number of connections.

Each of those addresses needs to have a receive adjacency - either a /32 or a /128 - and vpp needs to answer (proxy) arps or neighbor discovery requests for the addresses.

Template Parameters
client_index- opaque cookie to identify the sender
context- sender context, to match reply w/ request
is_ipv6- 1 for ipv6, 0 for ipv4
vrf_id- fib table / vrf id for local adjacencies
first_address- first address that TCP will use
last_address- last address that TCP will use
