[j-nsp] tos value of return traffic

[Bit Gossip]

Experts,
is it possible to set the value of return traffic from RE so that it is
set to a specific ip-prec or dscp value?

I have tested the following behaviour on MX480 Junos 9.5, where the MX
is the server:
- PING: a client ping the MX using tos=x, the Mx replies with same TOS=x
- SSH: a client establishes an ssh session with the Mx using TOS=x, the
Mx replies with TOS=0 for the first packets and then switches to
TOS=0x10
- TELNET: same as SSH
- SNMP: Mx replies to snmp queries with TOS=0 no matter how the query is
sent.
