The following are RA policy limitations.
As a result of a general limitation on CoA, a maximum of 32 bridge hosts can be updated. This limitation exists in the case of BRG.
RA policies are not supported for DSM.
RAs are configured to be sent at certain intervals. It is highly recommended that this interval is considered when configuring the prefix lifetimes. For example, if the interval is configured for one hour and the prefix lifetime is configured for 30 minutes, the (SLAAC) host is removed from the BNG before the next RA is sent.
If the parameters within the RA policy are modified, the parameters only take effect on the next interval.
