This requirement is not applicable for the DODIN Backbone. Review the router configuration and determine if filters are bound to the external interfaces to drop all IPv6 packets containing a Destination Option header with option type values of 0x05 (Router Alert) or 0xC2 (Jumbo Payload). The following example will block any inbound IPv6 packet containing a Destination Option header with option type values of with option type values of 0x05 (Router Alert) or 0xC2 (Jumbo Payload): Step 1: Verify that all external IPv6-enabled interfaces have an IPv6 filter as shown in the example below. interfaces { ge-0/0/0 { unit 0 { family inet6 { filter { input IPV6-INGRESS-FILTER; } address 2001:1:0:146::1/64; } } } } Step 2: Verify that the IPV6 filter blocks all packets with a Destination Option header as shown in the example below. firewall { family inet6 { filter IPV6-INGRESS-FILTER { term DEST_ OPT_HEADER { from { next-header dstops; } then { syslog; discard; } } term ALLOW_TCP_ESTABLISHED { from { next-header tcp; tcp-established; } then accept; } term DENY_BY_DEFAULT { then { syslog; discard; } } } } } Note: Currently JUNOS has no method to filter option type within Destination Option header. Hence, all packets with the Destination Option header must be dropped. If the router is not configured to drop IPv6 packets containing a Destination Option header with invalid option type values, this is a finding.
