This sections describes the limitations and restrictions that are applicable to the BWG feature in Cisco 
IOS Release 12.4(24)YG3, along with workarounds to the same:.

To reduce the CPU usage during bootup, disable logging to the console terminal by configuring the 
no logging console global configuration command.

To ensure that the HSRP interface does not declare itself active until it is ready to process a peers 
Hello packets, configure the delay period before the initialization of HSRP groups with the standby 
delay minimum 100 reload 100 interface configuration command under the HRSP interface.

When a session with PPPoE host and IP host is cached and revived before session cache timeout, 
both the PPPoE and IP hosts are retained, although only the DHCP host has to be retained.

In the case of a static IP host, after a cached session is revived, the static IP host is deleted, and only 
the DHCP host is revived.

WiMAX modem ID not included in AAA messages.

For WiMAX wholesale PPPoE customers using the BWG bridging feature, some of the PPPoE tags 
are malformed. These malformed tags cause issues when connected to either an ASR-1000 as a 
BRAS, or a 7301 as an ISG LAC. Attributes circuit-id-tag, remote-id-tag, and formatted-clid added 
by the BWG bridging code are skipped because the length of the tag is zero. Because these attributes 
are not properly recognized by ISG or ASR, the generated AAA messages do not contain important 
information such as the identity of the WiMAX modem.
