Re: How to share Routing info. in IPSPs communication at M3UA level

Thanks for instant response , it means after receiving ASPUP-ACK message 
by IPSP-A , IPSP-A should be send REGREQ to IPSP-B to register itself. 
Like this...
                          IPSP-A                           IPSP-B
                     |                                |
                     |-------------ASP Up------------>|
                     |<----------ASP Up Ack-----------|
                           |                                |
                     |----------- REG REQ (RKa)------>|(?)
                     |<---------- REG RSP (RCb)-------|
                           |                                |
                     |<------- ASP Active(RCb)--------|  RC: Routing 
Context
                     |-----ASP Active Ack (RCb)------>|      (optional)
                     |                                |
                     |                                |
                     |<=========  DATA (RCb) ========>|
                     |                                |
                     |<-----ASP Inactive (RCb)--------|  RC: Routing 
Context
                     |----ASP Inactive Ack (RCb)----->|      (optional)
                     |                                |
                     |<-----------ASP Down------------|
                     |---------ASP Down Ack---------->|
                     |                                |

Now my question is this, How will IPSP-B generate Routing Context(RCb) 
from Routing Key(RKa) of IPSP-A? Is there any algorithm to do this? thanks 
in advance...


With Regards,
Dheeraj

Dheeraj.Dubey,

The RC can be provisioned at either or both sides.  A side not 
provisioning
the RC may register a routing key with the other.  The exchange is the 
same
as for AS-SGP registration where the IPSP registering behaves like the AS
and the IPSP providing registration behaves like the SGP.
