When load balancing gateway (sgw/pgw) selection with SRV records, how is gateway selected for the second PDN (IMS)? For example: customer has 8 co-located sgw/pgw pair nodes, 3 of which support IMS but other 5 - don't. IMS capacity differs for the nodes supporting it. Is it possible to proportionally load them by IMS subscribers? Default PDNs are balanced between all 8 nodes with different weights either.
Currently default PDNs balancing works fine, but second PDNs are distributed between 3 IMS-supporting gateways evenly despite of the diferent weights.
