Thanks Qin. I checked and I think a few things that we agree previously haven't yet been incorporated: * In Sn 6.12.3.2, regarding the confusion between the second paragraph (begining "In the case of a provider-managed or co-managed connection, ...") and the bullet about direction - I think we agreed to delete the paragraph (at least, you asked on the list if anyone objected and I didn't see any replies). This was issue 9 in my comments on draft-02. * The provider address and mask are now optional in the case of DHCP, as agreed; however, in the case of static, they are still marked as mandatory. I think the following leaves need to have mandatory removed as well (issue 11 from draft-02) o l3vpn-service/sites/site/site-network-accesses/site-network-access/ip-connection/ipv4/addresses/provider-address o l3vpn-service/sites/site/site-network-accesses/site-network-access/ip-connection/ipv4/addresses/mask o l3vpn-service/sites/site/site-network-accesses/site-network-access/ip-connection/ipv6/addresses/provider-address o l3vpn-service/sites/site/site-network-accesses/site-network-access/ip-connection/ipv6/addresses/mask * In the filters container/choice, we agreed to add 'when' statements for each case based on the type, to prevent invalid combination of the type and filter lists as in the example I posted. (Issue 13 from draft-02). * For the address-allocation-type leaves, I saw you removed the default (as agreed) but also added 'mandatory true' (which was not discussed). Making these leaves mandatory does not address the problem - if anything, it makes it worse. (Issue 15 from draft-02) Two new comments: 1. Under the cloud-access list, the "authorized-sites" and "denied-sites" have been added back in, in draft-03. These were previously removed because they duplicate the functionality in the 'list-flavour' choice. 2. There are a number of leaves that are marked as mandatory or have defaults, which I think should not be - sorry for not raising this earlier, actually it was only just pointed out to me by someone else: 1. l3vpn-service/sites/site/security/encryption/layer - this should either be optional, or have a 'when' statement that means it only exists when encryption is enabled. If encryption is disabled, there is no need to specify the layer. 2. l3vpn-service/sites/site/security/encryption/encryption-profile/profile - same 3. l3vpn-service/sites/site/service/qos/qos-profile/qos-profile (and same under site-network-accesses) - I'm not sure why this choice is mandatory, that means one of the options has to be specified for both the site and the site-network-access. I think the intent is that it is optional in both places, so it can be specified in one or the other. 4. l3vpn-service/sites/site/site-network-accesses/site-network-access/service/multicast/multicast-address-family/ipv[46] - IPv4 has default true but IPv6 has default false; I think they should both be default false.
