IPv6 Applications
Examples of the IPv6 applications supported by the TiMOS include:
• IPv6 Internet exchange peering — Figure 4 shows an IPv6 Internet exchange where
multiple ISPs peer over native IPv6.

• IPv6 transit services — Figure 5 shows IPv6 transit provided by an ISP.

Note: In SR OS 12.0.R4 and later, any function that displays an IPv6 address or prefix
changes to reflect rules described in RFC 5952, A Recommendation for IPv6 Address Text
Representation. Specifically, hexadecimal letters in IPv6 addresses are now represented in
lowercase, and the correct compression of all leading zeros is displayed. This changes
visible display output compared to previous SR OS releases. Previous SR OS behavior can
cause issues with operator scripts that use standard IPv6 address expressions and with
libraries that have standard IPv6 parsing as per RFC 5952 rules.
