Hello,   When using an XR router as a dhcp relay agent (or proxy if you want), is there a way to specify the default router field in the DHCP server response? According to my customer they are doing this with another brand router in which the dhcp server sends the response and omits the default-router information and the router inserts this information in the response.    Can this be done on a Cisco XR router? If yes, how? Thanks! c. ... View more

Hi,   I'm implementing a BNG setup that requires me to format the username sent to a radius server for IPoEv6 authentication (fiber access). Customer requirement is that the username is created through the use of two fields: dhcpv6-interface-id and remote-id-tag. The problem I'm faced with is that the remote-id-tag attribute is coming in with extra characters that the ONT/OLT attach at the front of this field. For example: we're receiving "000007db302f332f30" instead of only "302f332f30" which is what we actually need from the remote-id-tag. (dhcpv6-interface-id is coming in as we expect it).   RP/0/RSP0/CPU0:BNG#show subscriber manager sadb Tue Feb 25 07:07:58.548 UTC Sublabel: 0x000000c5 Node_ID: 00000020 Signature: 0xabcdef12 Version: 1 Rev: 20 Length: 443 Attribute list: 5635102fbdb8 1: protocol-type len= 4 dhcpv6 2: dhcp-client-id len= 10 0x00-0x03-0x00-0x01-0xf4-0xb5-0xaa-0x95-0x65-0x7a(type :0x00, *******ez) 3: port-type len= 4 Virtual IP over QinQ 4: inner-vlan-id len= 4 12(c) 5: outer-vlan-id len= 4 400(190) 6: client-mac-address len= 14 f4b5.aa95.657a 7: parent-if-handle len= 4 1120(460) 8: remote-id-tag len= 18 000007db302f332f30 <-----   This string (000007db302f332f30) if converted to ASCII reflects the slot where this ONT resides, in this case "something+Û+0/3/0". Customer requirement mandates that we use "0/3/0" as part of the username, along with the information in dhcpv6-interface-id. I've been told by TAC that the problem is the 0000007 which is not printable by BNG (the documentation they sent me points to option82 in an ASR1k, I'm working with options 18 and 37 on an ASR9k), which forces the box to send the HEX string as is, instead of printing it (ASCII).   So, here's a few question to see if some of you have an idea how to deal with this.   - Does the BNG support a way to truncate the remote-id-tag attribute so that we only process/send the characters we need? - If yes, can you provide a sample of how to achieve this? - If this cannot be solved by the BNG itself and I'm not allowed to do this in the radius server (at least, at this point, I'm not allowed), can you thing of another solution?   Thanks for your help!

Hi,    Can anyone point to an updated document regarding the status of Netflow or a better alternative today? What is being used in the service provider industry and how? What is Cisco's preferred technology/product?   Thanks! c. ... View more

Hi,    Is BFD over a 9000v that hosted by a CRS running 5.3.4 supported?   I have a CRS/9000v connected to an ASR920 that is correctly running BFD with another ASR920, but it won't come up vs the CRS/9000v.

Hi,   I have an ASR1001x and want to enable the "neighbor x.x.x.x send-label" command, but it's not available to me. I have an IPB license, but I thought since licensing seems to be honor-based that the command would be available on all flavors even without a license present. Is this the case of will the command become unavailable if the correct license is not present?   Thanks in advance! c.     XXXXXX(config-router)#address-family ipv6 ?   flowspec   Address Family modifier   multicast  Address Family modifier   mvpn       Address Family modifier   unicast    Address Family modifier   vrf        Specify parameters for a VPN Routing/Forwarding instance   <cr>       <cr>   XXXXXX(config-router)#address-family ipv6 uh XXXXXX(config-router)#address-family ipv6 uni XXXXXX(config-router)#address-family ipv6 unicast ?   vrf   Specify parameters for a VPN Routing/Forwarding instance   <cr>  <cr>   XXXXXX(config-router)#address-family ipv6 unicast XXXXXX(config-router-af)#nei XXXXXX(config-router-af)#neighbor 1.1.1.1 ?   activate                 Enable the Address Family for this Neighbor   additional-paths         Negotiate additional paths capabilities with this neighbor   advertise                Advertise to this neighbor   advertise-map            specify route-map for conditional advertisement   advertisement-interval   Minimum interval between sending BGP routing updates   aigp                     Enable a AIGP on neighbor   allow-policy             Enable the policy support for this IBGP Neighbor   allowas-in               Accept as-path with my AS present in it   announce                 Announce RPKI State using an Extended Community   as-override              Override matching AS-number while sending update   capability               Advertise capability to the peer   default-originate        Originate default route to this neighbor   dmzlink-bw               Propagate the DMZ link bandwidth   filter-as                filter-as   filter-list              Establish BGP filters   inherit                  Inherit a template   maximum-prefix           Maximum number of prefixes accepted from this peer   next-hop-self            Disable the next hop calculation for this neighbor   next-hop-unchanged       Propagate next hop unchanged for iBGP paths to this neighbor   override-capability-neg  Override capability negotiation   prefix-list              Filter updates to/from this neighbor   remove-private-as        Remove private AS number from outbound updates   route-map                Apply route map to neighbor   route-reflector-client   Configure a neighbor as Route Reflector client   send-community           Send Community attribute to this neighbor   slow-peer                Configure slow-peer   soft-reconfiguration     Per neighbor soft reconfiguration   soo                      Site-of-Origin extended community   translate-update         Translate Update to MBGP format   unsuppress-map           Route-map to selectively unsuppress suppressed routes   weight                   Set default weight for routes from this neighbor   XXXXX(config-router-af)     ...
