All leased line terminal users, accessing BSE applications for trading and related functions are requested to add below mentioned secondary DNS entry in your terminal.  This is one-time change.

Currently, only Preferred DNS server IP is mentioned i.e. 10.1.125.122.  Now, one more IP needs to be added as Secondary DNS in Alternate DNS server – 10.1.22.162

Below is a view of terminal after adding secondary DNS.

With the addition of secondary DNS entry it will help in seamless resolution of leased line based URLs when operating from Primary site or from Disaster site.
