Hello Gokhan Gumus,
AFAIK this is not possible at the moment since flows are not shared between
MSDPCs even inside same MX box let alone different physical boxes.
So if R1 goes down the:
1/ TCP flows need to reestablish starting from 3-way handshake
2/ UDP flows with ALG need to reestablish starting from scratch (every ALG
has different procedures)
3/ non-ALG UDP flows _can_ continue as if nothing happened depending on
protocol, e.g. p2p UDP flows will resume from last xferred piece
4/ ICMP flows continue as if nothing happened
If you need physical-box-redundant NAT I'd suggest to use SRX cluster.

Subject: [j-nsp] NAT Redundancy on Juniper routers
Hi all,
I am trying to achieve redundancy on Juniper routers while performing NAT.
I have two Juniper MX960 router on the backbone with VRRP setup.I am
configuring NAT on R1 successfull.Same NAT rules are existing on the other
router but on R2,static route which is pointing sp interface is
deactivated.Is there anyway to achieve automatic failover capability on
NAT?In other words if something happened on R1, can R2 handle all NAT
process without doing anything?
Kind regards,
Gokhan Gumus
