This helps in determining the exact path a PW will take through the provider network (especially when there is ECMP). <br />Can someone highlight this process in more detail as to how the control word helps in this PW traceroute ?<br /><br />thanks<br />UsmanUnknownhttps://www.blogger.com/profile/02169280474344083036noreply@blogger.comtag:blogger.com,1999:blog-1727036611545335768.post-57309705457044611172009-07-23T15:26:29.629+05:302009-07-23T15:26:29.629+05:30Hi Shivlu,

However, the control word is required for Frame Relay and ATM AAL5 transport types.<br /><br />Regards,<br />Jatil ThakoreJatil Thakorehttps://www.blogger.com/profile/10865148647629249923noreply@blogger.com
