Hi Peter, All, Let me chime in.
When the L-bit is set in an ASLA TLV, then for all applications marked, indeed only legacy attributes can be used. Of course an ASLA TLV with the L-bit set is a valid ASLA advertisement. That is not the point. Read the text in chapter 4.2: > When the L-flag is set in the Application Identifier Bit Mask, all of > the applications specified in the bit mask MUST use the legacy > advertisements for the corresponding link found in TLVs 22, 23, 25, > 141, 222, and 223 or TLV 138 or TLV 139 as appropriate. This clearly says that when the L-bit is set, the LEGACY ADVERTISEMENTS have to be used. However chapter 6.1 is saying that legacy advertisements can only be used for RSVP-TE, SR-Policy and LFA. So in my opinion the draft is saying the opposite and legacy advertisements MUST NOT be used for flex-algo. Hence, I suggest that we should make it explicit clear that L-bit set for flex-algo is MUST NOT be allowed.

ASLA with L-bit pointing to legacy TLV is NOT considered legacy advertisement.

It says that if L-flag is set, all apps mentioned in the bitmask MUST use the legacy advertisement to derive the value of the attribute. It does NOT say that ASLA TLV with L-bit set means "using legacy advertisements". It does not. thanks, Peter > ... > When the L-flag is set in the Application Identifier Bit Mask, all of > the applications specified in the bit mask MUST use the legacy > advertisements for the corresponding link found in TLVs 22, 23, 25, > 141, 222, and 223 or TLV 138 or TLV 139 as appropriate. > > Regards, > Rudy > > -----Original Message----- > From: Lsr <[email protected]> On Behalf Of Peter Psenak > Sent: Thursday, September 3, 2020 9:55 AM > To: Shraddha Hegde <[email protected]>; [email protected]; > [email protected]; Robert Raszuk <[email protected]> > Cc: Christian Hopps <[email protected]>; > [email protected]; Les Ginsberg (ginsberg) > <[email protected]>; [email protected]; [email protected]; Acee > Lindem (acee) <[email protected]> > Subject: Re: [Lsr] WG Last Call for draft-ietf-lsr-flex-algo > > Hi Shraddha, > > On 03/09/2020 05:39, Shraddha Hegde wrote: >> Peter, >> >> In order to make the document clearer on this point, I would like the >> text below to be added to section 11 to make it explicit that setting the >> L-bit is valid for flex-algo for ISIS. >> >> ============= >> Section 11. >> >> “The ASLA TLV in ISIS supports the L-Bit as described in section 4.2 >> of [draft-ietf-isis-te-app].
