This is performed by means of using public-key self-signed certificates created by each master controller. CPsec is a secure form of communication between a controller and APs to protect the control plane communications. You create an initial CPsec Control Plane Security. If a managed device is unable to contact the Mobility Master to obtain it's own certificate, it will not be able to certify the APs, and those APs can not communicate with their managed device until Mobility Master- managed device communication has been re-established. If the Mobility Master has any associated managed device, the Mobility Master sends a certificate to each managed device, which in turn sends certificates to their own associated APs. The managed device certifies its APs by issuing them certificates. using public-key self-signed certificates created by each Mobility Master. Remote APs are deplyed at branch office sites and are connected to the central network on a WAN link. or remote APs Remote APs extend corporate network to the users working from home or at temporary work sites. Campus APs are deployed as part of the indoor campus solution in enterprise office buildings, warehouses, hospitals, universities, and so on. communications between a managed device and campus APs Campus APs are used in private networks where APs connect over private links (LAN, WLAN, WAN or MPLS) and terminate directly on controllers. IPsec is a protocol suite for secure IP communications that authenticates and encrypts each IP packet in a communication session. This value is SR OS proprietary.You are here: Home > Control Plane Security > Control Plane SecurityĪrubaOS supports secure IPsec Internet Protocol security. A value of (0x2) indicates the modified SPF algorithm, which removes from the topology the node that is backed up by the backup node SID. One octet identifying the algorithm the prefix SID is associated with. Multi-Topology ID, as defined in RFC 4915. These must be zero when sent and are ignored when received. If set, the SID is a backup SID for the prefix. This flag is used by the Protection using backup node SID feature. If not set, then the value/index carried by this sub-TLV has global significance. If set, the value/index carried by the prefix SID has local significance. If not set, the prefix SID carries an index.

If set, the prefix SID carries an absolute value. If set, any upstream neighbor of the prefix SID originator must replace the prefix SID with a prefix SID having an Explicit-NULL value (0 for IPv4) before forwarding the packet. If set, the SID is advertised from the Segment Routing Mapping Server functionality as described in I-D.filsfils-spring-segment-routing-ldp-interop. If set, the penultimate hop must not pop the prefix SID before delivering the packet to the node that advertised the prefix SID.

Table: OSPF control plane extension flags Flag Table: OSPF control plane extension fields lists OSPF control plane extension flag values. | Flags | Reserved | MT-ID |Algorithm (0x2)| The new Algorithm (0x2) field and values are used by this feature. The values used in the Flags field and in the Algorithm field are SR OS proprietary. The following shows the encoding of the prefix SID sub-TLV to indicate a node SID of type backup and to indicate the modified SPF algorithm in the SR Algorithm field. This is in addition to the default supported algorithm ‟IGP-metric-based-SPF” of value 0. All routers supporting OSPF control plane extensions must advertise support of the new algorithm ‟Backup-constrained-SPF” of value 2 in the SR-Algorithm TLV, which is advertised in the Router Information Opaque LSA.
